When setting up proportions remember to set up both fractions with the same units in the numerator and the denominator.

Once the proportion is set up, cross multiply, and solve for the variable.

Problem 1. A boat can travel 126 miles on 18 gallons of gas. How much gas will it need to go 175 miles?

Problem 2. A car can travel 442 miles on 13 gallons of gas. How far can it travel on 4 gallons of gas?

A boat can travel 144 miles on 16 gallons of gas. How much gas will he need to travel 171 miles?
