There are 56 boys and girls altogether.
23 of the number of boys is 14 more than the number of girls.
- How many boys are there?
- How many more boys than girls are there?
(a)
Number of boys = 3 u
Number of girls = 2 u - 14
Number of children
= 3 u + 2 u - 14
= 5 u - 14
5 u - 14 = 56
5 u = 56 + 14
5 u = 70
1 u = 70 ÷ 5 = 14
Number of boys
= 3 u
= 3 x 14
= 42
(b)
Number of girls
= 56 - 42
= 14
Number of more boys than girls
= 42 - 14
= 28
Answer(s): (a) 42; (b) 28
