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

• math -

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.

• I'M SORRY!! -

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
