The table shows the number of books the children had borrowed. A total of 69 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
= 1 + 1 + 9
= 11
(b)
Total number of books borrowed by each child who borrowed 1 to 4 books each
= 1 x 1 + 2 x 1 + 3 x 9 + 4 x 6
= 54
Number of children who borrowed 5 books each
= (69 - 54) ÷ 5
= 15 ÷ 5
= 3
Answer(s): (a) 11; (b) 3
