Unit Rate/Unit Price

A unit rate is a comparison of two different quantities where one of the quantities is expressed as a quantity of one. For example, if you earn $50 for 2 hours of work, the unit rate is $25 per hour.

To calculate the unit price, divide the total price by the number of units. For example, if a 3-pound bag of candy costs $6.04, the unit price is $6.04 ÷ 3 = $2.01 per pound.

$2.40 ÷ 4 = $0.60 per apple.

$200 ÷ 8 hours = $25 per hour.

45 problems ÷ 2 minutes = 22.5 problems per minute.

The 3-pound bag is the better buy because its unit price is lower.

$3.18 per slice of pizza is an example of a unit rate.

Multiply the unit price by the number of items. For example, if 1 apple costs $0.60, then 6 apples cost $0.60 × 6 = $3.60.

120 miles ÷ 3 hours = 40 miles per hour.

Unit Rate = Total Quantity ÷ Number of Units.
