Adam puts 160 children into 2 groups.
There are 70 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
= 160 ÷ 2
= 80
Number of boys in each group
= 80 - 70
= 10
(b)
Total number of boys
= 2 x 10
= 20
(c)
Total number of girls
= 160 - 20
= 140
Number of less boys than girls
= 140 - 20
= 120
Answer(s): (a) 10; (b) 20; (c) 120
