Question

Reuben drove 268 miles using 12 gallons of gas. At this rate, how many miles would he drive using 9 gallons of gas?

Answer 1

This question calls for ratios. Reuben drove 268 miles with 12 gallons. 268 divided by 12 is $22\frac{1}{3}$, so he can drive 22 and one third of a mile with one gallon. Multiply that by 9 and you will get 201 miles, which is how much he can drive using 9 gallons of gas
