Question

If there is a boy to girl ratio of 3:4, how many girls are there if there

are 18 boys? Complete the table to determine the answer.
Boys
Girls

Answer 1

24 girls.
Because the ratio of boys to girls is 3:4, for every 3 boys there are 4 girls. 3 goes into 18 6 times and because the number of boys has increased by 6x, all we need to do is multiply 4 by 6 which is 25

Answer 2

24 Girls

Explanation:

3/4 = 18/x

3*x = 18*4

3x=72

3x/3=72/3

x=24
