A car used 13 gallons of gas to travel 156 miles how far can the car travel on 18 miles gallons of gas

216 miles

Step-by-step explanation:

Let's set up a proportion using the following setup.

miles/gallons=miles/gallons

We know the car can travel 156 miles on 13 gallons. We don't know how many miles the car can travel on 18 gallons, so we can say the car can travel x miles on 18 gallons.

156 miles/13 gallons=x miles/18 gallons

156/13=x/18

We want to find out what x is. Therefore, we have to get x by itself. x is being divided by 18. The inverse of division is multiplication, so we can multiply both sides by 18.

18*156/13=x/18*18

18*156/13=x

18*12=x

216=x

x=216 miles

The car can travel 216 miles on 18 gallons of gas.
