Answer:
Step-by-step explanation:
This is a unit problem.
[tex]\frac{28mpg}{8.25g}[/tex]
If you notice in that ratio, there is a "g" in both the numerator and the denominator which will cancel out, leaving you only with the label of miles, which is what you are looking for (since "how far can she drive..." is a distance thing). 28 then only needs to be divided by 8.25 to see how many miles this is.
[tex]\frac{28mpg}{8.25g}=3.3939393939[/tex] miles which, in an improper fraction, is
[tex]\frac{112}{33}[/tex] miles
