In order to solve this problem, first we’ll have to figure out the proportionality ratio between the gallons I put in my car and the amount I paid. $30 ÷ 10 gallons = $3/gallon ($ per gallon) After, once we know that the ratio is $3/gallon, we need to calculate how many gallons we can put in the tank with $18. $18 ÷ $3/gallon = 6 gallons.Definition: Constant of Proportionality. In a proportional relationship, the values for one quantity are each multiplied by the same number to get the values for the other quantity. This number is called the constant of proportionality.
