maddielb · Answer

Well if it went 191.25 miles and it gets 25.5 miles per gallon, you just divide 191.25 by 25.5 and get 7.5 gallons

danjs · Answer

You are converting miles , into the gallons used from the given ratio.
$$\frac{ 191.25~mi }{ 1 }*\frac{ 1~gal }{ 25.5~mi }=7.5~~gal$$

danjs · Answer

you want a fraction..
$$\frac{ 7.5 }{ 1 }*\frac{ 10 }{ 10 }=\frac{ 75 }{ 10 } = \frac{ 15 }{ 2 }$$
