1. Unit Rates
Objective: I will compute unit rates associated with ratios of fractions with like or different units and use unit ratios to convert rates
MAFS.7.RP.1.1: Compute unit rates associated with
ratios of fractions, including ratios of lengths, areas and
other quantities measured in like or different units.

2. Do Now
If a person walks ½ mile in each ¼ hour, compute the unit rate

3. Unit Rates
During their last workout, Izzy ran 2 ¼ miles in 15 min, and her friend Julia ran 3 ¾ miles in 25 minutes. Which girl ran more miles per minute?

4. Unit Rates Method 1: Create a table: 2. Change mixed fractions: Izzy
2 ¼ miles
15 min
Julia
3 ¾ miles
25 min

7. Unit Rates
Your turn: A turtle walks 7/8 of a mile in 50 minutes. What is the unit rate expressed in miles per hour?

8. Unit Rates
Reflection: How is the unit rate calculated? Can we calculate unit rates when both values in the ratio are fractions? Explain.
