To write a proportion that shows how much 5 gallons of gas will cost, we can set up the following proportion:

15 gallons / $45 = 5 gallons / x

This proportion states that the ratio of the number of gallons to the cost is the same for both situations. The unknown cost, represented by x, is what we want to find.
