Our company parking lot has cars, trucks, and motorcycles. The ratio of cars, trucks, and motorcycles is \(1:6:4\)  If there are a total of  42 cars and trucks, then how many motorcycles are there?

Cars and trucks are   ( 1 + 6) / (1 + 6 + 4)  =  7/11 of the total number, N, of  vevicles

 

So...

 

(7/11) N  =  42

 

N =   42 ( 11/7)  =  66   vehicles in total

 

So....there are   66 - 42  =  24 motorcycles
