How To Solve Unit Rates

First, you look at what the problem asks you. For example, say the question says, " You run at a rate of 3 miles every 30 minutes. How many minutes does it take you run a mile?" What you would do is divide 30 by 3, because you have to find how many for 1 unit, and that would tell you how many minutes it takes you to run a mile, which in this case would be 10. In unit rates, the key is to narrow down the two units until one unit becomes a 1. It is usually the higher number divided by the lower number. You can rewrite the unit rate as '10 minutes per mile' or as a fraction. ( 10 min. / 1 mile )

Decide whether the rates are equal.
