The ratio of boys to girls in a group is 5:3. If there are 16 more boys than girls, work out how many boys there are.

[5/8N] =G + 16 [G=B].................(1)

[3/8N] =G....................................(2)

Use substitutions to get:

N =64 - Total number of boys and girls.

G =24 - Number of girls.

B =24 + 16 =40 - number of boys.

Boys make up 5 / (5+3) = 5/8 of the group girls make up 3/8

5/8 x = 16 + 3/8 x (given)

2/8 x = 16

x = 64 in the group 5/8 are boys 5/8 * 64 = 40 boys
