Which unit rate is equivalent to 13 Miles Per Gallon?

A. 26Miles/2gallons B. 2Gallons/26Miles C. 39Miles/4Gallons D. 4Gallons/39 Miles

Step-by-step explanation:

1. Write the given unit rate as a fraction

13 miles/1 gallon

2. Find out which one matches

A. 26 miles/2 gallons

     = 13 miles/1 gallon.

We know that A is correct. But, just to double check, we will solve the other  

problems.

B. 2 gallons/26 miles

   = 1 gallon/13 miles.

C. 39 Miles/4 gallons

   = 9.75 miles/gallon

D. 4 gallons/39 miles

   = 1 gallon/9.75 miles

None of these equations equal the first.

Remember that in these types of problems, it may be difficult to know whether they want you to also say "B" is equal. Use your context clues. If they only allow one answer, choose only A. But, if during your math unit, the answers to these types of problems always have two answers, choose both A and B.
