Reading the Text Rip Van Winkle was a lazy man who lived in a small Dutch village. He liked to wander through town with his pet dog, Wolf, and tell stories to the children. Rip’s wife, Dame, did not like his laziness and used to shout at him for not doing any work. To escape her shouting, he often went to a nearby inn to relax and exchange stories with his friends. The forest was the only other place where Rip felt safe from his wife’s shouting. One wintry afternoon, Rip and Wolf went into the hills, again, to escape inn Dame’s shouting. They spent the whole day hunting for squirrels, though they did not catch anything. When it was time to return home, they heard a voice calling Rip. They thought it was Dame until they saw a small man dressed in strange clothes. The little man was carrying a heavy drum and asked for Rip’s help. Rip hurried to help him. ninepins As Rip and the little man carried the drum, they heard a loud booming sound like thunder. After walking for quite a while, they came to an open field, where Rip saw many little bearded men playing a game called ‘ninepins’. The noisy game was being played with huge balls that made a booming echoed sound when they hit one another. Rip recognised the sound that he had been hearing all along. The sound of their bowling echoed throughout the mountains. The drum that Rip had helped to carry was filled with a tasty drink, which the small men shared with Rip. After drinking three full glasses, he began to feel sleepy. The Sun had gone down and the noise of the bowling continued, as Rip fell asleep in the moonlight. tattered When Rip woke up, he was surprised! Wolf was gone, Rip’s rusted clothes were tattered and torn, his gun had rusted, and his beard had grown – a foot in length! He looked around to see if he could find the little bearded men, but he could not recognise the place. Rip decided to go home, though he knew he would be scolded by his wife for being careless again! 2 1/7/2019 3:17:22 PM NR_BGM_9789386663504 MAPLE G05 INTEGRATED TEXTBOOK TERM 2_Text.pdf 4

When Rip entered his village, he stopped in surprise. There were many new buildings. The children of the village were curious and gathered around him, whispering. He did not recognise any of them. He went to his own house and found it empty, silent. He called out his wife’s name and the names of his children, but no one answered. The house looked lonely and empty. Now even more confused than before, Rip walked through town to the inn. However, the old inn was gone. There was a bigger, newer inn in its place. Outside the inn, people were gathered around, talking about an election. Rip enquired about his friends. He was told that the inn manager had been dead for eighteen years and that the schoolmaster he knew had moved from the village. Finally, Rip asked if anyone knew who Rip Van Winkle was. A young woman holding a baby stepped forward, saying that Rip was her father and that he’d gone out hunting twenty years ago and never returned. Rip then realised that he had been asleep for twenty years! Rip recognised the young woman as his daughter Judith now grown. He told her that he, in fact, was her father. Rip then told everyone the story of where he had been for the last twenty years. No one believed him. Finally, they called an old, wise man named Peter Vanderdonk, who knew many stories about the village. Peter listened as Rip repeated his tale. He claimed that Rip had met some ghosts. A few of the villagers thought Rip Van Winkle was crazy. But others believed him. Rip Van Winkle went to live with his daughter, Judith, and her family. He began telling stories to the children, just as he used to earlier. And not surprisingly, he told his own story frequently. Occasionally, he would hear thunder in the mountains, but he never went into the forest again. He did not want to lose another twenty years. – Adapted from ‘Rip Van Winkle’ by Washington Irving Let Us Discuss 1) Who was Rip Van Winkle?

He strolled into the big grey wood, And saw the mushrooms where they stood. Then suddenly, his eyes grew round And round! What had he found? A tiny girl sat in the grass, Staring, scared, under the big brown mass! ‘Don’t be afraid my friend’, he said, A smile across his face then spread. ‘What is your name? My name is Shyam, And I don’t mean you any harm!’ But when she heard the words he said, Out she stepped, with cheerful tread, ‘Hi there Shyam, I’m Ann’, said she, ‘I’m a spirit of plant and tree.’ 8 1/7/2019 3:17:23 PM NR_BGM_9789386663504 MAPLE G05 INTEGRATED TEXTBOOK TERM 2_Text.pdf 10

Reading the Text Summer vacations were over. Days of slurping ice cream, drinking mango panna and lazing around in the afternoons were over. But Ninu wanted to stay in bed till late. ‘Wake up, Ninu! Do you want to be late for school on the very first day after slurping the holidays and set a bad example?’ Ninu’s mother scolded her. ‘I am waking up, Maa’, said Ninu, rubbing her eyes. nibbling Ninu quickly brushed, got dressed and sat down for summer break breakfast. As she sat nibbling at the mint chutney sandwich, her mind was repeating Miss Leela’s words: ‘Everyone has to speak about the places that they travel to during their summer vacations. It accounts for 50 percent of the total marks. And everybody will need to speak on the first day after the summer break.’ ‘I am leaving for work. I have kept your lunch ready’, her mother said. Ninu’s father had passed away when she was just three years old. Her mother had started stitching clothes to support them financially. She could earn enough to send her daughter to a good school but not enough to go on vacations. ‘What will I tell Miss Leela? I did not travel to any place during the summer vacation. Yes, I will tell her this, because this is the truth and we should always tell the truth.’ No! Ninu shuddered at the thought of losing fifty percent marks. What was she supposed to do? shuddered The students rushed into their classrooms eagerly on the first day of school. Everyone was busy chatting with each other. Ninu sat alone in a corner, thinking hard. Miss Leela walked in, and the class greeted her in a loud and monotonous voice, ‘Good morning Misssssss!’ ‘Good morning, students. So good to see all of you back. Before I ask you to speak about the place you travelled to during the summer holidays, let me tell you about my trip.’ It seemed as though Miss Leela was in a good mood. ‘I visited Shimla with my family. It is a beautiful hill station and the capital of Himachal Pradesh. Everything was so different there — the food, the climate, the trees. It was a lovely trip!’ she said. One by one, the students began talking about their holidays. beamed 14 1/7/2019 3:17:23 PM NR_BGM_9789386663504 MAPLE G05 INTEGRATED TEXTBOOK TERM 2_Text.pdf 16

Putul spoke about her experience next. ‘Miss, I went to my village in Odisha, near Bhubaneswar. The best part was the trip to the Nandan Kanan Zoo. I saw crocodiles, snakes . . .’Yikes, thought Ninu. How could someone enjoy snakes and crocodiles? They are disgusting. yikes The next to speak was Steve. ‘Miss, we went to Paris this vacation. We visited many museums there. I was so bored. We also visited the Eiffel Tower. The best part was the visit to Disneyland.’ The entire class was listening eagerly to his description. Ninu felt uncomfortable in her seat as it was her turn to speak next. What will she say? Everybody would laugh at her. She stood up, took a deep breath and spoke. ‘Miss, this summer vacation I visited the library.’ ‘What?’ Rima, who sat beside her, started laughing. Soon, the entire class was making fun of her. Ninu’s eyes filled with tears. She stared at the blackboard, feeling embarrassed. ‘Enough, all of you! Let Ninu complete what she has to say.’ Miss Leela nodded at Ninu with a smile, encouraging her. Ninu cleared her throat, wiped her face and began. ‘This summer vacation, I decided to read as many books as I could because Dr Seuss says in one of his books: “The more you read, The more things you will know, The more that you learn, The more places you’ll go.” When I read different books, I was transported to another world. I read books about magical trees, animals that could talk, princes and princesses, witches and giants, magical spells and curses. I read about different cultures. I read about great people of the world — M K Gandhi, Martin Luther King, Albert Einstein and Mother Teresa. I visited several places while sitting in the library, and I learned a lot.’ Miss Leela rose from her seat and hugged Ninu. ‘To explore the world, we don’t have to travel. All we need is an open mind and a willingness to learn. Everything around us is waiting to be explored, and waiting to tell us a story. Well done, Ninu!’ – Surbhi Sarna Oh!

R3 Reading Comprehension Passage 1 Read the passage and answer the questions given below. The Tyrannosaurus Rex (T-Rex) lived in Laramidia, which is present-day western North America. It lived in the Upper Cretaceous Period, between 85–66 million years ago. The T-Rex is among the last non-flying dinosaurs. One of the largest land predators ever known, the T-Rex was nearly 40-feet long and 13-feet wide at the hips. It weighed four to seven tons! Scientists know from studying its fossils that the T-Rex had an enormous skull and a long, massive tail to support its weight. Despite its hands being relatively small, they were powerful, with two clawed digits (like fingers). The hind legs of the dinosaur were extensive and mighty. The T-Rex possessed the most ferocious bite of any land animal on Earth. Its jaw was at least four-feet thick and contained 50–60 teeth, many of which were up to nine inches long. Its strong teeth could remove flesh from its prey and cut it in its mouth. 500 pounds of flesh and bone in one bite! Also, there were rotting bacteria between its teeth, giving it a ‘septic’ bite. If it wounded but failed to kill prey, they would die of fatal infections anyway! In 1990, Sue Hendrickson, a famous fossil hunter, discovered the most complete fossil of a T-Rex skeleton ever found (85% complete). Eventually, it was sold to the Field Museum of Natural History for a whopping eight million dollars. The museum spent over 25,000 person- hours in removing rock from the bones.

The emperor was very sad after the queen’s death. He would often sit in his beautiful garden and watch a fleet of swans, a flock of ducks or a herd of deer that roamed about freely. The deer had been gifted by a king of a faraway country. But nothing seemed to cheer him up. A troupe of dancers also performed at the court but to no avail. Everyone wanted to help the emperor come out of his sadness, but nothing seemed to work. One day, a priest in the palace saw a few children playing with dolls. The dolls made shadows on the floor that appeared to dance while the children played. They tried to catch the shadows and laughed as they played.

Reading the Text It was the first day of my winter holidays. Every winter, we plan road trips to explore new places. It is my family’s favourite time to travel! I remember, last December, on a cold morning, we began our journey to Santiniketan. Did I tell you that Santiniketan is about a hundred kilometres away from my hometown, Krishnanagar in central West Bengal? That day, Baba woke me up at five in the morning. By the time I got ready, Maa had prepared some snacks. We quickly got into the car. Driver Uncle told us that it will take us around three hours to reach Santiniketan. As the car moved out of the town, I looked at the vast stretch of golden paddy fields. There were just a few people here and there. The winter sun was shining bright, and it was turning a little hot. After about two hours, we were all hungry. Baba saw a tea-stall and asked Driver Uncle to stop. We climbed out and stretched ourselves as Driver Uncle got us cups of tea and biscuits. Baba told me there was still an hour to go before we paddy reached Santiniketan. Maa, who’s a good photographer, started clicking pictures of men and women going about their daily work. In the meantime, Baba ordered several plates of bread-omelette. They were delicious! We started our journey again, and Maa began to sing as she looked out of the window. The sky was shining blue, and the fields were all green and golden. The flowers of the gulmohar tree formed a red roof across the road. It was beautiful! By 9 o’clock, we reached Santiniketan and went straight to the gulmohar Rabindra Bhavan Museum. I was absolutely wide-eyed as the guide took us around, and one by one opened doors to times gone by. He narrated stories of the great poet and writer, Rabindranath Tagore. Tagore had spent most of his life in Santiniketan and had founded the famous Visva Bharati University. It was his vision that transformed Bolpur from a little town into the international educational centre that is known as Santiniketan today. I was thrilled to look at the manuscripts of Tagore’s poems and songs. Maa hummed some songs of Rabindra Sangeet as we moved from one room to another. By the time we finished exploring the museum and the vast campus around it, we were all tired and thirsty. Driver Uncle suggested that we go and have lunch. thrilled He took us to a quaint little place to eat. From the manuscript 22 NR_BGM_9789386663504 MAPLE G05 INTEGRATED TEXTBOOK TERM 2_Text.pdf 24 1/7/2019 3:17:24 PM

outside, it looked nothing like a restaurant. We were all confused. Baba asked, ‘Are you sure that we will get food here?’ Driver Uncle gave a small smile and walked briskly towards the clay hut. He called out, ‘Kamala! Four meals please!’ Soon, Kamala Aunty, came out of the hut with her two daughters. We sat on a briskly mat under a jackfruit tree right outside her house. She then served us delicious home-cooked food for lunch. I did not know that a one-day trip would have so many new experiences to offer. Kamala Aunty was a very inspiring woman. She cooked daily for her family as well as for the tourists. I played for some time with her daughters. Then, Driver Uncle told us that it was time to leave. Next, we headed to Khoai, a dry forest region with red soil. At Khoai, we walked around as the rays of the afternoon sun fell on us. The air carried a slight chill. It was so calming that we felt sleepy. We sat down to rest near a group of trees. We heard the rustling of the leaves as the sonajhuri trees danced to the tune trotting of the breeze. Their tiny yellow flowers fell on us, sonajhuri and the whole forest seemed to be filled with gold. Nearby, the Kopai river flowed to the rhythm of a trotting horse. It was magical! The rhythm was suddenly broken by the sound of gathered foot bells. A Baul troupe had gathered on the banks a Baul singer of Kopai to perform their songs and dance. Driver Uncle told us that the Baul singers love to be close to nature. They travel around to perform their music. We listened to the music as the Sun went down. Time just flew! Soon it was time to go back home. As our car moved out of Santiniketan, the red dusk lingered behind as if saying goodbye. I have such wonderful memories of that day.

Chapter Time 7 Let Us Learn About • converting larger units to smaller units of time and vice versa. • word problems based on time. • adding and subtracting time. Concept 7.1: Convert Time Think Pooja’s father spends 120 minutes every week reading the newspaper. Pooja wants to know the number of hours he spends reading the newspaper. Can you find that? Recall In Class 4, we have learnt about time and its units such as minutes, hours, days and so on. Let us revise them by solving the following. 1) Draw hands on a clock to show: a) 7:33 p.m. b) 4:45 a.m. c) 1:28 p.m. d) 1450 h NR_BGM_9789386663504 MAPLE G05 INTEGRATED TEXTBOOK TERM 2_Text.pdf 33 1 1/7/2019 3:17:24 PM

2) Answer these questions. a) How many hours are there in a day? b) How many days are there in a year? c) How many days make a week? d) How many days are there in a leap year? e) How many days does the month of December have? & Remembering and Understanding We have learnt different units of measuring time such as seconds, minutes, hours, and days. The larger units of measuring time are weeks, months and years. Let us now learn the conversion of time. To convert a smaller unit of time to a larger unit, we divide. To convert a larger unit of time to a smaller unit, we multiply. Days to hours and hours to days 1 day = 24 hours 1 hour = 1 day 24 Hours to minutes and minutes to seconds 1 hour = 60 minutes = 60 min 1 minute = 60 seconds Seconds to minutes and Seconds to hours 1 minute = 1 hour 60 1 second = 1 minute 60 1 second = 1 × 1 hour = 1 hour 60 60 3600 Consider a few examples of conversion of time. Example 1: Convert the following into hours. a) 13 days b) 2 days 16 hours 2 1/7/2019 3:17:24 PM NR_BGM_9789386663504 MAPLE G05 INTEGRATED TEXTBOOK TERM 2_Text.pdf 34

Solution: a) 1 day = 24 h Therefore, 13 days = 13 × 24 h = 312 h b) 1 day = 24 h 2 days 16 h = (2 × 24 h) + 16 h = 48 h + 16 h = 64 h Therefore, 2 days 16 hours is 64 hours. Example 2: Convert the following into minutes. a) 7 hours b) 6 hours 25 minutes Solution: a) 1 hour = 60 minutes Therefore, 7 hours = 7 × 60 min = 420 min b) 1 hour = 60 minutes 6 hours 25 min = (6 × 60 min) + 25 min = 360 min + 25 min = 385 min Therefore, 6 hours 25 minutes = 385 minutes Example 3: Convert the following into seconds. a) 5 h b) 28 min c) 3 days d) 6 weeks Solution: a) 1 hour = 60 × 60 s Therefore, 5 h = 5 × 60 × 60 s = 18000 s b) 1 min = 60 s Therefore, 28 min = 28 × 60 s = 1680 s c) 1 day = 24 h = 24 × 60 × 60 s Therefore, 3 days = 3 × 24 × 60 × 60 s = 259200 s d) 1 week = 7 days Therefore, 6 weeks = 6 × 7 × 24 × 60 × 60 s = 3628800 s Example 4: Convert the following: a) 28 min into hours and days b) 560 min into hours and min c) 240 s into min, hours and days Time 3 NR_BGM_9789386663504 MAPLE G05 INTEGRATED TEXTBOOK TERM 2_Text.pdf 35 1/7/2019 3:17:24 PM

Solution: a) 1 min = 1 h 60 So, 28 min = 28 × 1 h= 28 h= 7 h 60 60 15 11 1 min = 60 × 24 days 1 1 7 1 7 Therefore, 28 min = 28 × 60 × 24 days = 15 × 24 days = 360 days 77 So, 28 min = 15 h = 360 days. b) 1 min = 1 h 60 1 1 So, 560 min = 560 × 60 h = (540 × 60 h + 20 min) = 9 h 20 min Therefore, 560 min = 9 h 20 min. 1 11 111 c) 1 s = 60 min = 60 × 60 h = 60 × 60 × 24 days So, 240 s = 240 × 1 min = 4 min 60 11 4 min = 4 × 60 h = 15 h 115 h = 115 × 1 days = 1 days 24 360 Therefore, 240 s = 4 min = 1 h = 1 days. 15 360 Application Let us solve a few real-life examples where conversion of time is used. Example 5: An aeroplane stops for 600 seconds at Mumbai airport. For how many minutes does it stop? Solution: We know that 1 minute = 60 seconds. So, 1 second = 1 minutes. 60 Therefore, 600 seconds = 600 minutes = 10 minutes. 60 Thus, the aeroplane stops for 10 minutes at Mumbai airport. Example 6: During a television programme, there were 10 breaks of 48 seconds each. For how many minutes did the breaks last? Solution: There are 10 breaks each of 48 seconds. Therefore, total time in seconds = 48 seconds × 10 = 480 seconds 4 1/7/2019 3:17:24 PM NR_BGM_9789386663504 MAPLE G05 INTEGRATED TEXTBOOK TERM 2_Text.pdf 36

We know that, 1 minute = 60 seconds. 480 Thus, 480 seconds = 60 minutes = 8 minutes So, the breaks lasted for a total of 8 minutes. Example 7: In January, Seema played for 30 minutes every day. For how much time did she play in that month? Give your answer in seconds. Solution: In January, Seema played for 30 minutes every day. Number of days in January = 31 Number of minutes she played in January = 30 minutes × 31 days = 930 minutes 1 minute = 60 seconds So, 930 minutes = 930 × 60 seconds = 55800 seconds Therefore, Seema played for 55800 seconds in January. Higher Order Thinking Skills (H.O.T.S.) Let us learn the conversion of some more units of time. Consider the following examples. 1 Example 8: Roopa travels for 3 2 h each day while her sister travels for 3840 seconds. Who travels for a longer duration? Solution: Time for which Roopa travels = 3 h 30 min Time for which her sister travels = 3840 sec = 3600 sec + 240 sec 1 = 1 h + (240 × 60 ) min (Converting seconds to minutes and hours) = 1 h 4 min As 3 h 30 min > 1 h 4 min, Roopa travels for a longer duration. Example 9: Seeta takes 5 days 6 hours and 15 minutes to complete her Science project. How much time in seconds does she take to complete the project? Time 5 NR_BGM_9789386663504 MAPLE G05 INTEGRATED TEXTBOOK TERM 2_Text.pdf 37 1/7/2019 3:17:24 PM

Solution: Time taken by Seeta to complete the project = 5 days 6 hours and 15 minutes We know that, 1 day = 24 hours 1 hour = 60 minutes So, 5 days = 5 × 24 hours = 120 hours. 120 hours + 6 hours = 126 × 60 minutes = 7560 minutes To find time taken in seconds, we know that 1 minute = 60 seconds So, 7560 minutes + 15 minutes = 7575 × 60 = 454500 second. Therefore, Seeta took 454500 seconds to complete the project. Concept 7.2: Add and Subtract Time Think Pooja spends 30 minutes playing football and 40 minutes playing basketball. She also spends 1 hour 10 minutes playing tennis every Sunday. Do you know how much time she spends playing? Recall We have learnt the conversion of hours to minutes, minutes to seconds and vice-versa. Let us recall them by completing the given table. Hours Minutes Seconds 2 240 360 13 28800 6 1/7/2019 3:17:24 PM NR_BGM_9789386663504 MAPLE G05 INTEGRATED TEXTBOOK TERM 2_Text.pdf 38

& Remembering and Understanding Let us now understand the addition and subtraction of time through some examples. While adding time, we add the minutes (smaller units) first and then the hours (larger units). Sometimes, we may have to regroup the sum of the minutes. If the sum of minutes is 60, we convert it to 1 hour and add it to the hours. Let us see an example. Example 10: Add: 1 hour 35 minutes and 2 hours 45 minutes Solution: Steps Solved Solve these Step 1: Write both the numbers one Hours Minutes below the other. 1 35 +2 45 Step 2: Add hours and minutes Hours Minutes Hours Minutes separately, regrouping if needed. 1 35 1 20 +2 45 +3 50 3 80 Step 3: Check whether the minutes 80 minutes > 60 minutes Hours Minutes in the sum is greater than or equal to 60. If yes, then convert it into 2 30 hours. Step 4: Add the hours obtained 3 hours 80 minutes +2 20 in step 3 to the hours obtained in        step 2. 1 60+ 20 4 hours 20 minutes The sum is 4 hours 20 minutes. While subtracting, we subtract the minutes first (smaller units) and then the hours (larger units). Sometimes, we may have to regroup the hours. Let us see an example. Time 7 NR_BGM_9789386663504 MAPLE G05 INTEGRATED TEXTBOOK TERM 2_Text.pdf 39 1/7/2019 3:17:25 PM

Example 11: Subtract: 2 hours 35 minutes from 3 hours 10 minutes Solution: Steps Solved Solve these Step 1: Write both the numbers one below the other, such that Hours Minutes Hours Minutes the smaller number is subtracted from the larger one. 3 10 3 45 Step 2: Subtract hours and –2 35 –1 20 minutes separately, regrouping if needed. 10 minutes < 35 minutes. So, borrow 1 hour, that is, 60 minutes and add it to the Hours Minutes minutes. (10 + 60 = 70) 4 20 Step 3: Reduce the hours by Hours Minutes –2 40 1 and subtract the minutes as usual. 2 70 –2 35 35 Step 4: Subtract the hours and Hours Minutes Hours Minutes write the difference. 2 70 5 30 –2 35 –3 35 0 35 The difference is 35 min. Example 12: Subtract 4 h 42 min from 380 min. Hours Minutes Solution: We first convert 380 min to hours and minutes. 5 80 380 min = (300 × 1 h) + 80 min –4 42 60 1 38 = 5 h 80 min Therefore, the difference is 1 h 38 min. 8 1/7/2019 3:17:25 PM NR_BGM_9789386663504 MAPLE G05 INTEGRATED TEXTBOOK TERM 2_Text.pdf 40

Application Now let us solve a few examples where the addition and subtraction of time are mostly used. Example 13: A courier boy delivered letters for 2 hours 35 minutes and parcels for 3 hours 28 minutes in a day. For how long was he on the job? Solution: Time spent in delivering letters = 2 h 35 min Hours Minutes Time spent in delivering parcels = 3 h 28 min Total time spent on the job = 2 35 2 h 35 min + 3 h 28 min = 5 h 63 min +3 28 5 63 63 > 60 63 min = 1 h 3 min Therefore, the total time spent on job = (5 h + 1 h) + 3 min = 6 h 3 min. Example 14: On Saturday, Rima’s drawing class lasted for 2 hours 20 minutes, while on Sunday, it lasted for 1 hour 40 minutes. How much longer was the drawing class on Saturday? Solution: To find how much longer the drawing class on Saturday was, we must subtract 1 hour 40 minutes from 2 hours 20 minutes. Hours Minutes 2 h 20 min can be written as 1 h 80 min by regrouping. 1 80 So, on Saturday, Rima’s drawing class lasted 40 minutes – 1 40 longer. 0 40 Higher Order Thinking Skills (H.O.T.S.) Now let us solve a few more examples involving addition and subtraction of time. Example 15: Mr. Roy spends 1 hour 30 minutes in his garden every day. Mr. Pavan does the same for 50 minutes. How much more time does Mr. Roy spend than Mr. Pavan in his garden? Give your answer in seconds. Solution: Time spent by Mr. Roy in his garden = 1 hour 30 minutes Time spent by Mr. Pavan in his garden = 50 minutes To find the required, subtract 50 minutes from 1 hour 30 minutes. Time 9 NR_BGM_9789386663504 MAPLE G05 INTEGRATED TEXTBOOK TERM 2_Text.pdf 41 1/7/2019 3:17:25 PM

Now, we need to find the answer in seconds. Hours Minutes 1 minute = 60 seconds 1 30 40 minutes = 40 × 60 seconds = 2400 seconds Therefore, Mr. Roy spends 2400 seconds more in his –0 50 0 40 garden. Example 16: Sohan started preparing for his exam from 16th July. The exams were scheduled to begin 25 days later. On which date were the exams scheduled to begin? Solution: Start date of exam preparation = 16th July Preparation day for exams includes 16th July. So, subtract 15 days from 31 days of July. Number of days of preparation in July = 31 – 15 = 16 Days of preparation left in the month of August = 25 – 16 = 9 Therefore, the date when the exam begins is 10th August. Drill Time Concept 7.1: Convert Time 1) Convert into days. a) 4 years 5 weeks b) 3 years 10 days c) 2 years 15 days d) 4 years 20 days e) 1 year 3 weeks 2) Convert the given time to hours. a) 240 minutes b) 360 minutes and 3600 seconds c) 180 minutes d) 300 minutes and 3600 seconds 3) Word problems a) A bus takes 1 hour and 25 minutes to reach a bus stand. It stops 5 times for 45 seconds at each stop to pick up passengers. For how many minutes did the bus stop? b) Amit reached his house from school in 110 minutes.

Chapter Money 8 Let Us Learn About • u nitary method in money. • p roblems based on unitary method in money. • c hart of exchange rates. Concept 8.1: Unitary Method in Money Think Pooja’s father gave her a bill from a supermarket. Pooja found that there are addition, subtraction and multiplication operations in that bill. She wondered if she could use division too. Can you guess where and how each operation is used in a supermarket bill? Recall We have already learnt about mathematical operations such as addition, subtraction, multiplication and division. We have also learnt about decimals. Let us answer the following to recall the different operations involving money. a) ` 436.25 + ` 703.75 b) ` 565 − ` 209.50 c) ` 368.80 × 36 d) ` 911.25 ÷ 27 e) ` 495 ÷ 11 12 1/7/2019 3:17:25 PM NR_BGM_9789386663504 MAPLE G05 INTEGRATED TEXTBOOK TERM 2_Text.pdf 44

& Remembering and Understanding We use multiplication to find the value of many units from the value of a single unit. We use division to find the value of a single unit from the value of many units. We can also find the value of different number of units by following these two steps. Step 1: Find the value of a single unit from the value of the given units. Use division to obtain the same. Step 2: Using the value obtained in Step 1, find the value of many units. We need to use multiplication for the same. The method of finding the value of one unit and then finding the value of many units is called the Unitary Method. Let us now see a few examples to understand the unitary method better. Example 1: The cost of 12 erasers is ` 36. What is the cost of 18 erasers? Solution: The cost of 12 erasers = ` 36 Step 1: Cost of 1 eraser = ` 36 ÷ 12 =`3 Step 2: Cost of 18 erasers = 18 × ` 3 = ` 54 Therefore, 18 erasers cost ` 54. Example 2: Three pens cost ` 39. Find the cost of a dozen pens. Solution: Cost of 3 pens = ` 39 Step 1: Cost of 1 pen = ` 39 ÷ 3 = ` 13 Step 2: 1 dozen = 12 items Cost of a dozen pens = Cost of 12 pens = ` 13 × 12 = ` 156 Therefore, a dozen pens cost ` 156.

Example 3: The cost of 25 notebooks is ` 525. How many notebooks can be bought for ` 1575? Solution: Cost of 25 notebooks = ` 525 Cost of 1 notebook = ` 525 ÷ 25 = ` 21 Amount with which notebooks are to be bought = ` 1575 Number of notebooks that can be bought = Total amount ÷ Cost of each notebook = ` 1575 ÷ ` 21 = 75 Therefore, 75 notebooks can be bought. Application The unitary method can be used to compare two or more items. Consider these examples. Example 4: Mona observed that a pack of four soaps, each of 150 g, costs ` 60. Another pack of six soaps, each of 100 g costs ` 54. Which pack should Mona buy so that she spends lesser amount of money? Solution: Weight of 4 soaps, each of 150 g = 150 g × 4 = 600 g Cost of 4 soaps = ` 60 Cost of 1 g of soap = 60 ÷ 600 = ` 1 = 1 × 100 paise = 10 paise 10 10 Weight of 6 soaps, each of 100 g = 100 g × 6 = 600 g Cost of 6 soaps = ` 54 So, cost of 1 g soap = 54 ÷ 600 = ` 9 = 9 × 100 paise = 9 paise 100 100 Since 9 paise < 10 paise, Mona has to buy the pack of 6 soaps of 100 g each to spend a lesser amount of money. 14 1/7/2019 3:17:25 PM NR_BGM_9789386663504 MAPLE G05 INTEGRATED TEXTBOOK TERM 2_Text.pdf 46

Example 5: A set of eight plastic sharpeners costs ` 48.80. A set of six steel sharpeners costs Solution: ` 48.60. Which set of sharpeners is expensive? `6.10 `8.10 Cost of 8 plastic sharpeners = ` 48.80 Cost of 1 plastic sharpener = ` 48.80 ÷ 8 )8 `48.80 )6 `48.60 Cost of 6 steel sharpeners = ` 48.60 − 48 − 48 8 6 −8 −6 Cost of 1 steel sharpener = ` 48.60 ÷ 6 0 0 −0 −0 Since ` 8.10 > ` 6.10, the set of steel sharpeners is expensive. 0 0 Example 6: )The cost of 17 kg of guavas is ` 552.50. 3 2.50 What is the cost of 10 kg of guavas? 17 552.50 Solution: Cost of 17 kg of guavas = ` 552.50 - 51 42 Cost of 1 kg of guavas = ` 552.50 ÷ 17 - 34 = ` 32.50 85 - 85 Cost of 10 kg of guavas = ` 32.50 × 10 00 = ` 325 - 00 Therefore, 10 kg of guavas cost ` 325. 00 Higher Order Thinking Skills (H.O.T.S.) Different countries of the world have different currencies. We see a chart in banks called the chart of exchange rates. It shows the money (in rupees) that we get in exchange for the money of other countries. Observe the chart given below. This gives the exchange rates as on 23rd January 2017. Country Currency Indian Rupees U.S.A. Dollar 68.12 England Pound 84.98 China Yuan 9.94 Sri Lanka Rupee (SL) 0.46 U.A.E. Dirham 18.54 Germany Euro 73.13 Money 15 NR_BGM_9789386663504 MAPLE G05 INTEGRATED TEXTBOOK TERM 2_Text.pdf 47 1/7/2019 3:17:26 PM

Let us see a few examples on the exchange of money using this chart. Example 7: Rita’s aunt from the U.S. gifted her 15 US dollars. Rita used ` 300 for her dress from that amount. How much money was left with her? Give your answer in Solution: rupees. (Hint: 1 US dollar = ` 64.14, as of December 19, 2017) 1 US dollar = ` 64.14 15 US dollars = ` 64.14 × 15 = ` 962.1 Amount Rita spent for her dress = ` 300 Amount left with Rita = ` 962.1 – ` 300 = ` 662.1 Therefore, Rita has ` 662.1 left with her. Example 8: Ravi works for a Sri Lankan company for a salary of 1000 SL (Sri Lankan Rupees). Suresh works for a company in China for a salary of 1200 yuans. Who earns more in terms of Indian currency? (Hint: 1 SL = ` 0.42 and 1 yuan = ` 9.69 ) Solution: We know that 1 Sri Lankan Rupee = ` 0.42 1000 Sri Lanka Rupees = ` 0.42 × 1000 = ` 420 Also, 1 Chinese yuan = ` 9.69 1200 yuans = 1200 × ` 9.69 = ` 11628 As, ` 11628 > ` 420, Suresh earns more than Ravi.

Chapter Fractions - I 9 Let Us Learn About • e quivalent fractions and cross- multiplying equivalent fractions. • finding the missing numerators or denominators in the fractions. • reducing fractions using division and H.C.F. • the term 'unlike fraction' and comparing unlike fractions. • a dding and subtracting unlike fractions. Concept 9.1: Equivalence of Fractions Think Pooja eats two pieces of a cake that was cut into four equal pieces. Farhan eats three pieces of cake of the same size that was cut into six equal pieces. Do they eat the same amount of cake? Recall In Class 4, we have learnt about equivalent fractions. Let us revise them here. Suppose a pizza is cut as shown. Rohan eats 2 of the pizza. Then the piece of pizza he gets 8 is = . NR_BGM_9789386663504 MAPLE G05 INTEGRATED TEXTBOOK TERM 2_Text.pdf 49 17 1/7/2019 3:17:26 PM

Suraj eats 1 of the pizza. Then the piece of pizza he gets is . 4 We see that the pieces of pizza eaten by both are of the same size. So, we say that the fractions 2 and 1 are equivalent. 84 21 We write them as 8 = 4 . Recall the following: • The multiples of a number are obtained by multiplying it by 1, 2, 3 and so on. For example, the multiples of 6 are 6, 12, 18, 24, 30, 36 and so on. • The numbers that divide a given number exactly are called its factors. For example, the factors of 6 are 1, 2, 3 and 6. • Equivalent fractions are obtained by multiplying or dividing the numerator and the denominator of the given fraction by the same number. For example, 1 , 3 , 5 , 2 and so on, are equivalent fractions. 7 21 35 14 & Remembering and Understanding Fractions that denote the same part of a whole are called equivalent fractions. Let us now understand the process used to check the equivalence of the given fractions. Cross-multiplication: To check if two fractions are equivalent, we cross multiply them. In cross-multiplication, we multiply the numerator of the first fraction by the denominator of the second. Then, we multiply the denominator of the first by the numerator of the second. If the cross products are equal, the given fractions are equivalent. Otherwise, they are not equivalent. Example 1: Check if these fractions are equivalent. a) 3 and 9 b) 1 and 2 5 15 36 Solution: a) 3 and 9 5 15 18 1/7/2019 3:17:26 PM NR_BGM_9789386663504 MAPLE G05 INTEGRATED TEXTBOOK TERM 2_Text.pdf 50
