Number of rooms in the school = 26
Number of plants in each room = 4
So, the total number of plants = 26 x 4 = 104
Number of cups needed for each plant = 2 cups
Then, the total number of cups required for 104 plants = 104 x 2 = 208
Hence, we need 208 cups of water for all the plants.
Make the Best Story Problem
Each line gives a story. You have to choose the question which makes the best story problem.
(1) A shopkeeper has 50 boxes. There are 48 fruits in one box.
Explain why (a) and (c) are not good choices.
Option (a) is not a good choice because price is not given in the story
Option (c) is not a good choice because total number of boxes is given in the story.
(2) 352 children from a school went on a camping trip. Each tent had a group of 4 children.
(3) A shopkeeper has 204 eggs. He puts them in egg trays. Each tray has 12 eggs.
(4) The cost of one book is Rs 47. Sonu buys 23 books.
Practice Time
Do these divisions. Check your results by multiplication.
(a) 438 ÷ 9 (b) 3480 ÷ 12 (c) 450 ÷ 7
(d) 900 ÷ 10 (e) 678 ÷ 6 (f) 2475 ÷ 11
(a)
Quotient = 48, Remainder = 6 and Divisor = 9.
Checking:
Divisor x Quotient + Remainder = 9 x 48 + 6 = 438 = Dividend
(b)
Quotient = 290, Remainder = 0 and Divisor = 12.
Checking:
Divisor x Quotient + Remainder = 12 x 290 + 0 = 3480 = Dividend
(c)
Quotient = 64, Remainder = 2 and Divisor = 7.
Checking:
Divisor x Quotient + Remainder = 7 x 64 + 2 = 450 = Dividend
(d)
Quotient = 90, Remainder = 0 and Divisor = 10.
Checking:
Divisor x Quotient + Remainder = 10 x 90 + 0 = 900 = Dividend
(e)
Quotient = 113, Remainder = 0 and Divisor = 6.
Checking:
Divisor x Quotient + Remainder = 6 x 113 + 0 = 678 = Dividend
(f)
Quotient = 225, Remainder = 0 and Divisor = 11.
Checking:
Divisor x Quotient + Remainder = 11 x 225 + 0 = 2475 = Dividend
