How do you calculate a unit rate with fractions?

Back

To calculate a unit rate with fractions, divide the numerator by the denominator of the fraction to find the rate per one unit of the other quantity. For example, if you have 3/4 of a gallon of paint that covers 1/2 of a wall, the unit rate is (3/4) ÷ (1/2) = 3/2 or 1.5 gallons per wall.
