Three quarters of the cars in a parking garage are black, 4/7 of the remaining cars are blue, and the rest are silver. If there are 9 silver cars, how many cars are in the parking garage?

3/4 are black. 

 

1/4 * 4/7 = 1/7 are blue

 

1 - (3/4 + 1/7) = 1 - (25/28) = 3/28 are silver. 

 

3/28 = 9
 

1/28 = 3

 

3 x 28 = 84, which is your answer :)
