2 answers:
The answer is 15 action movies were rented
One way to solve is to set up a proportion. If the ratio of comedies to action is 4:3 (also can be written as the fraction 4/3) then you can set 4/3 equal to 20/x. 4/3 = 20/x then cross multiply. 4·x = 3·20 4x = 60 Then divide both sides by 4 x= 15
