Tonya's car averages 240 miles for each 10 gallons of gasoline. How many gallons of gasoline will the car need travel 216 miles?

240/10 = 24 miles per gallon.
216/24 = ?

1) The first part of the of the problem means that for every 10 gallons of gas, you can drive 240 miles.
2) You can make a ratio where 240mi/10gal = 216mi/Xgal.
3)Then cross multiply to get 240X=2160.
4) X = 9gal

i found out it was 24 miles per gallon and divided 216 and 24 then multiplied the answer by 24 and i got
(216/24)=(9 x 24)= 216
so the mathematical answer is 9

I am still stumped on this question... What should I divide 216 by?
