The table shows the number of books the children had borrowed. A total of 77 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
= 9 + 3
= 12
(b)
Total number of books borrowed by each child who borrowed 1 to 4 books each
= 1 x 9 + 2 x 3 + 3 x 7 + 4 x 4
= 52
Number of children who borrowed 5 books each
= (77 - 52) ÷ 5
= 25 ÷ 5
= 5
Answer(s): (a) 12; (b) 5
