The table shows the number of books the children had borrowed. A total of 75 books were borrowed by the children.
- How many children borrowed 2 books or less?
- How many children borrowed 5 books?
(a)
Number of children who borrowed 2 books or less
= 4 + 6
= 10
(b)
Total number of books borrowed by each child who borrowed 1 to 4 books each
= 1 x 4 + 2 x 6 + 3 x 7 + 4 x 7
= 65
Number of children who borrowed 5 books each
= (75 - 65) ÷ 5
= 10 ÷ 5
= 2
Answer(s): (a) 10; (b) 2
