Adam puts 90 children into 3 groups.
There are 20 girls and some boys in each group.
- How many boys are there in each group?
- How many boys are there altogether?
- How many less boys than girls are there?
(a)
Number of children in each group
= 90 ÷ 3
= 30
Number of boys in each group
= 30 - 20
= 10
(b)
Total number of boys
= 3 x 10
= 30
(c)
Total number of girls
= 90 - 30
= 60
Number of less boys than girls
= 60 - 30
= 30
Answer(s): (a) 10; (b) 30; (c) 30
