What is a Unit Rate?
Understanding Unit Rate
A unit rate is a comparison of two different quantities, where one of the quantities is expressed as a value of one. This concept is essential in everyday life, from shopping for groceries to understanding speeds in driving. For example, if you buy 6 apples for $3, the unit rate would be the cost of one apple, which is $0.50.
