The table shows the number of books the children had borrowed. A total of 66 books were borrowed by the children.
- How many children borrowed 3 books or less?
- How many children borrowed 5 books?
(a)
Number of children who borrowed 3 books or less
= 5 + 9 + 3
= 17
(b)
Total number of books borrowed by each child who borrowed 1 to 4 books each
= 1 x 5 + 2 x 9 + 3 x 3 + 4 x 6
= 56
Number of children who borrowed 5 books each
= (66 - 56) ÷ 5
= 10 ÷ 5
= 2
Answer(s): (a) 17; (b) 2
