The ratio of boys to girls in Mr. Johnson's after-school club is the same as the ratio of boys to girls in Ms. Greene's after-school club.

There are 4 boys and 12 girls in Mr. Johnson's club.

There are 6 boys in Ms. Greene's club.

to get the number of girls in greene's club we represent it by x

and intrepret it in ratio

4:6 = 12: x

4/6 = 12/x

cross multiply

4x = 6 x12 = 72

x = 72/4 = 18

there are 18 girls in greene's club
