Your car can go 375 miles on 12 gallons of gas. How far can you go on just 7 gallons of gas?

Cross multiply this equation. You will have:
375 x
 = 
12 7
After cross multiplying you will find that on 7 miles of gas you can drive 218 & 3/4 miles. 
That equation didn't come out correctly!
It should be:
375/12 = x/7
(It will be in fraction form)DO NOT SOLVE IT BY DIVINDING! THAT WILL NOT WORK!
STEP 1: MULTIPLY 375 BY 7 TO GET 2625
STEP 2: MULTIPLY 12 BY X TO GET 12X
STEP 3: SET UP YOUR EQUATION
EQUATION: 12X=2625
STEP 4: DIVIDE BOTH SIDES BY 12
X=218.75
