What are Rates and Unit Rates?

Rates are a ratios of two numbers with different units
Unit rates are rates (ratios with different units) that have a 1 in the denominator
Anything divided by 1 can just be rewritten as itself without the division

1. This is a ratio with 60 miles as the numerator and 3 hours as the denominator
1. This is a ratio with 40 words in the numerator and 2 minutes in the denominator
1. If the rate is in fraction form, the denominator is 1
1. Notice that this is just a rate with a denominator equal to 1
2. A rate is a ratio of numbers with different units
3. Remember to keep the units in the same place of the fraction as before
4. So "miles" stays in the numerator and "hour" stays in the denominator
