There are 146 girls and boys altogether.
45 of the number of girls is 16 more than the number of boys.
- How many girls are there?
- How many more girls than boys are there?
(a)
Number of girls = 5 u
Number of boys = 4 u - 16
Number of children
= 5 u + 4 u - 16
= 9 u - 16
9 u - 16 = 146
9 u = 146 + 16
9 u = 162
1 u = 162 ÷ 9 = 18
Number of girls
= 5 u
= 5 x 18
= 90
(b)
Number of boys
= 146 - 90
= 56
Number of more girls than boys
= 90 - 56
= 34
Answer(s): (a) 90; (b) 34
