The table shows the number of books the children had borrowed. A total of 57 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
= 6 + 3 + 2
= 11
(b)
Total number of books borrowed by each child who borrowed 1 to 4 books each
= 1 x 6 + 2 x 3 + 3 x 2 + 4 x 1
= 22
Number of children who borrowed 5 books each
= (57 - 22) ÷ 5
= 35 ÷ 5
= 7
Answer(s): (a) 11; (b) 7
