Of 99 cars making up a freight train, 62 are boxcars. What fraction of the cars are not boxcars?

Answer 1

The number of non box cars is the number of cars minus the number of boxcars.

This is 99 cars - 62 boxcars = 37 non boxcars

The fraction is the number of nonboxcars divided by the total cars

or

37/99.
