The ratio of boys to girls on the bus is 3:2. If there are 18 boys on the

bus, how many girls are on the bus?

12 girls 18 boys Total 30 students

Step-by-step explanation

x=number of girls

18/3 = x/2

3x=18*2

3x=36

x=12

Other proof

x = number of groups

3x + 2x = 30

5x=30

x=6

3 * (6) + 2 * (6) = 30

18+12=30
