 | The Basics:   Rates

A rate is a ratio that compares two numbers with differing units.  Remember, a ratio compares two numbers with the same units, such as 5 feet to 2 feet  or   25 mph to 100 mph.   A rate would instead show a comparison such as miles per hour, gallons per minute, price per pound.

A unit rate is a rate in which the denominator is equal to one or 1 unit.
