Question

Of 57 cars making up a freight train, 23 are boxcar. 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 57 cars - 23 boxcars = 34 non boxcars

The fraction is the number of nonboxcars divided by the total cars
or
34/57

total no of cars =57

Cars which are not boxcars =57-23=34

23/34×57=1339/34
