Given:
At 9 gallons, it can travel 396 miles.
Find: At one gallon, it can travel ___ miles.
Solution:
First, let's fill in the number line with the information we have.
Then, to find the missing value ?, let's do cross multiplication.
Then, divide both sides of the equation by 9.
Therefore, on 1 gallon of gas, the car can travel 44 miles.
