A vehicle uses 1 1/8 gallons of gasoline to travel 13 1/2 miles. At this rate, how many miles can the vehicle travel per gallon

valentina_108 [34]

Answer:

12 miles

Step-by-step explanation:

The problem above is related to the topic on "Equivalent Ratios." The missing term above is <em>"the number of miles that the vehicle can travel per gallon of gasoline."</em> In order to find this term, you have to use the "cross products."

Let n be the missing term.

$1\frac{1}{8} gallons$ / $13\frac{1}{2} miles$ = $\frac{1 gallon}{n}$

$\frac{9}{8} gallons$ / $\frac{27}{2} miles$ = $\frac{1 gallon}{n}$

$\frac{9}{8}$ x n = $\frac{27}{2}$ x 1 gallon

n = $\frac{27}{2}$ ÷ $\frac{9}{8}$

n = $\frac{27}{2}$ x $\frac{8}{9}$

n = 12 miles

Therefore, the vehicle can travel 12 miles per gallon of gasoline.
