The table shows the number of books the children had borrowed. A total of 90 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
= 7 + 2
= 9
(b)
Total number of books borrowed by each child who borrowed 1 to 4 books each
= 1 x 7 + 2 x 2 + 3 x 4 + 4 x 8
= 55
Number of children who borrowed 5 books each
= (90 - 55) ÷ 5
= 35 ÷ 5
= 7
Answer(s): (a) 9; (b) 7
