Question

Sams car traveled 120 miles on 9 gallons of gasoline. Which fraction expresses the ratio of miles to gasoline ?

1) 4/3
2) 3/40
3) 3/14
4) 40/3

Answer 1

Choice 4.) 40/3

Explanation:

To find the fraction that expresses the ration of miles to gasoline We must find a number that both numbers can be divided by equally to simplify the fraction.

In this case the number 3 gets the job done.

120 ÷ 3 = 40

9 ÷ 3 = 3

So our ration of miles to gasoline is 40/3
