The table shows the number of books the children had borrowed. A total of 86 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
= 4 + 2 + 1
= 7
(b)
Total number of books borrowed by each child who borrowed 1 to 4 books each
= 1 x 4 + 2 x 2 + 3 x 1 + 4 x 5
= 31
Number of children who borrowed 5 books each
= (86 - 31) ÷ 5
= 55 ÷ 5
= 11
Answer(s): (a) 7; (b) 11
