Exp.
Such as if it took 3 gal. gas to go 60 mi how far can we go on 9 gal.
60 miles ???? 60 miles 3 180 mi.
_______ = ______ » _______ * _ = ______
3 gals. 9 gals. 3 gals. 3 9 gals.
So therefore we see that you could travel approximately 180 miles on 9 gallons of gas.
This method of solving these problems is called rationalizing the denominator in order to find a common denominator.
