Question

• 576 books are to be packed in boxes. If one box has 24 books, how many boxes are needed?
• 836 people are watching a movie in a hall. If the hall has 44 rows, how many people can sit in 1 row?
• A gardener bought 458 apple trees. He wants to plant 15 trees in each row. How many rows can he plant?
How many trees would be left over?

Answer 1

• Number of boxes required to pack 24 books = 1

There are 576 books that need to be packed in boxes.
∴ Number of boxes required to pack 576 books = 576 ÷ 24
= 24
Working:



Thus, 24 boxes are required to pack 576 books.

• Total number of people watching movie in the hall = 836

Number of rows in the hall = 44
∴ Number of people sitting in 1 row = 836 ÷ 44
= 19
Working:



Thus, 19 people are sitting in 1 row of the hall.

• Total number of apple trees bought by the gardener = 458

Now, the gardener wants to plant 15 trees in each row.
∴ Number of rows of apple trees that can be planted by the gardener = 458 ÷ 15

Working:



Quotient = 30
Remainder = 8
So, the gardener can plant 30 rows of apple trees and 8 trees will be left.
