4 Answers ID : in-4-multiplication [4] (1) 1248 km. The train travels 52 km in one hour. This means, the train will travel 24 times 52 km in one day because we have 24 hours in a day. Hence, the train will travel km = 1248 km in a day. (2) A) When we multiply 313 with 100, we simply put the number of zeros in 100 on the right hand side of 313. Hence, the answer is B) 2530 When we multiply 253 with 10, we simply put the number of zeros in 10 on the right hand side of 253. Hence, the answer is C) When we multiply 72 with 10000, we simply put the number of zeros in on the right hand side of 72. Hence, the answer is

5 D) ID : in-4-multiplication [5] When we multiply 196 with 10000, we simply put the number of zeros in on the right hand side of 196. Hence, the answer is (3) Rs. 272 Meenakshi ordered 3 burgers for Rs. 23 each. Total money she paid for burgers = Cost of one burger Number of burgers ordered = Rs = Rs. 69 Meenakshi ordered 5 sandwiches for Rs. 16 each. Total money she paid for sandwiches = Cost of one sandwich Number of sandwiches ordered = Rs = Rs. 80 Meenakshi ordered 3 sodas for Rs. 17 each. Total money she paid for sodas = Cost of one soda Number of sodas ordered = Rs = Rs. 51 Meenakshi ordered 3 pizzas for Rs. 24 each. Total money she paid for pizzas = Cost of one pizza Number of pizzas ordered = Rs = Rs. 72 Step 5 Hence, the total amount Meenakshi paid to the shopkeeper = The amount paid for burgers + The amount paid for sandwiches + The amount paid for sodas + The amount paid for pizzas = = 272

6 (4) A) ID : in-4-multiplication [6] In the given question, we have been asked to find the product of two numbers: Multiplicand: 6196 Multiplier: ( ) Here, we know the multiplier and multiplicand but the product is unknown. Remember, if we know the multiplier and the multiplicand, the product can be found by multiplying the multiplier and multiplicand. So, the product = 6196 ( ), Or , Or Hence, the product of 6196 ( ) is B) In the given question, we have been asked to find the product of two numbers: Multiplicand: 6465 Multiplier: ( ) Here, we know the multiplier and multiplicand but the product is unknown. Remember, if we know the multiplier and the multiplicand, the product can be found by multiplying the multiplier and multiplicand. So, the product = 6465 ( ), Or , Or Hence, the product of 6465 ( ) is

7 (5) 52 ID : in-4-multiplication [7] Total number of people who ate pizza slices = Number of Ram's friends + 1 (Ram himself) = = 26 Total number of slices eaten by each person = 2 Total number of slices eaten by Ram and his friends = Total number of people Total number of slices eaten by each person = 26 2 = 52 Hence, Ram had ordered 52 slices. (6) 52 According to the question, the total number of scales in the bag = 13 We are also given that there are 4 times as many sharpeners as scales in the bag. So, the number of sharpeners in the bag = 4 times the number of scales = 4 number of scales = 4 13 = 52 Hence, there are 52 sharpeners in the bag.

8 (7) A) five million eight hundred twenty-one thousand five hundred ten ID : in-4-multiplication [8] Let us first convert the given number into numerals: seven thousand three hundred sixty-nine = 7369 seven hundred ninety = 790 The product will be: Therefore, the product of seven thousand three hundred sixty-nine by seven hundred ninety is five million eight hundred twenty-one thousand five hundred ten. B) six hundred ninety-four thousand six hundred eight Let us first convert the given number into numerals: two thousand nine hundred ninety-four = 2994 two hundred thirty-two = 232 The product will be: Therefore, the product of two thousand nine hundred ninety-four by two hundred thirtytwo is six hundred ninety-four thousand six hundred eight.

9 (8) 1204 ID : in-4-multiplication [9] There are 7 days in a week. This means, the number of days in 2 weeks = 7 times 2 = 7 2 days = 14 days We need to calculate the number of roller skates manufactured in 2 weeks. This means, we need to calculate the number of roller skates manufactured in 14 days. Hence, the number of roller skates manufactured by the factory in 14 days = The number of roller skates manufactured by the factory in 1 day The number of days = = 1204 roller skates (9) km. Given, the train travels 710 km in one hour. This means, the train will travel 24 times 710 km in one day, because we have 24 hours in a day. Therefore, the train will travel km = km in a day.

10 (10) ID : in-4-multiplication [10] We know that there are 60 minutes in one hour and 24 hours in one day. The number of minutes in one day = The number of minutes in one hour The number of hours in one day = = 1440 minutes We also know that there are 30 days in the month of June. Hence, the number of minutes in the month of June = The number of minutes in one day The number of days in the month of June = = minutes (11) Rs One year has 12 months. This means, 5 years have 5 times 12 months = 5 12 months = 60 months. The amount of money Ria will earn in 5 years = The amount of money she will earn in 60 months = The amount of money Ria earns in one month 60 = Rs = Rs (12) a. 6 8 If we multiply the number of pencils in each row with the total number of rows, we can get the total number of pencils. Number of pencils = Number of rows pencils in each row = 6 8 = 48 Here, the expression used to find the total number of pencils is multiplication, that is, 6 8.

11 (13) d. 96 and ID : in-4-multiplication [11] We will go by the options in the given question. Option a: = , which does not match with the right hand side of the option. Option b: = 96000, which does not match with the right hand side of the option. Option c: = , which does not match with the right hand side of the option. Step 5 Option d: = , which matches with the right hand side of the given option. Step 6 Hence, option d is correct. (14) c. 8 (60 + 8) Here, we have to find the expression for We know, 68 = Replacing 68 by in the given expression: 8 68 = 8 (60 + 8) = (by using the distributive property of addition) We conclude that 8 68 can also be represented as 8 (60 + 8) and On observing the given options, we conclude that option c is the correct answer.

12 ID : in-4-multiplication [12] (15) A) 50 In the given question, we can see that 1484 is the product of two numbers: Multiplicand: 28 Multiplier: ( + 3) Here, we know the product and multiplicand, but the multiplier is not fully known. Remember, if we know the product and the multiplicand, the multiplier can be found by dividing the product by the multiplicand. So, the multiplier = = 53 Now we know: + 3 = 53 Here, we know the sum and one of the addends, but the second addend is not known. The other addend can be found by subtracting the known addend from the sum: Unknown addend = Sum - Known addend = 53-3 = 50 Hence, the missing number is 50.

13 ID : in-4-multiplication [13] B) 80 In the given question, we can see that 2759 is the product of two numbers: Multiplicand: 31 Multiplier: ( + 9) Here, we know the product and multiplicand, but the multiplier is not fully known. Remember, if we know the product and the multiplicand, the multiplier can be found by dividing the product by the multiplicand. So, the multiplier = = 89 Now we know: + 9 = 89 Here, we know the sum and one of the addends, but the second addend is not known. The other addend can be found by subtracting the known addend from the sum: Unknown addend = Sum - Known addend = 89-9 = 80 Hence, the missing number is 80.
