How can you tell if a rate is a unit rate?

A rate is a unit rate if it compares a quantity to one unit of another quantity. To identify a unit rate, check if the second quantity in the comparison is equal to one. For example, if you have a speed of 60 miles per hour, it indicates how many miles are traveled in one hour, thus making it a unit rate. If a rate is expressed as a fraction, you can simplify it to see if the denominator equals one.
