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.

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

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?

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

Unit Rates 3. Find ratio by dividing fractions:

Unit Rates Method 2: Use time clocks (make a diagram) Izzy Julia

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?

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