You can set up a ratio that looks like this: 126/6=294/x. It means that the total miles over gallons used is the same ratio. So you would cross multiply, getting 126x=294 times 6. Solve for x, which would be (294 times 6)/126.

126 miles<---> 6 gallons
294 miles<--->(294 / 126) x 6 gallons
= 294 / 21 gallons
= 42 / 3 gallons
= 14 gallons

Or...you could divide 126/6 equals 21mpg...thus 294/21 equals 14 gallons of gas...why use algebra when simple division works!
