Answer:

21 Miles per Gallon

Step-by-step explanation:

I assume you just have to change it into equal/equivalent fractions

[tex]\frac{7 mi}{1/3 gal}[/tex]

For the divison fraction, divide both the numerator and denominator by 1/3

[tex]\frac{7 / \frac{1}{3} }{\frac{1}{3}/\frac{1}{3} }[/tex], this equals to around [tex]\frac{21}{1}[/tex] (This'll make sense in a bit)

For the multiplication problem, Multiply both the numerator and denominator by 3

[tex]\frac{7 *3}{\frac{1}{3}*3 }[/tex], this also equals to around [tex]\frac{21}{1}[/tex]

Since both the division and multiplication both totaled to  [tex]\frac{21}{1}[/tex]

[tex]\frac{21 mi}{1 gal}[/tex]

= 21 miles per gallon

Hope this helps!
