What makes a ratio a rate




















For example, if you ran 70 yards in 10 seconds, you ran on average 7 yards in 1 second. Both of the ratios, 70 yards in 10 seconds and 7 yards in 1 second, are rates, but the 7 yards in 1 second is a unit rate. Ask: Now that you know what a unit rate is, what do you think a unit price is?

Students will say that it is the price of one item. If they don't, tell them what it is. Which store has the better deal? Students should say that we are trying to find out which is the better deal for carrots when thinking about the cost of each carrot. Ask: What would help us find the better deal? Students should say that if we find the unit price for the carrots at each store, we would know which was the better deal.

Say: Find the unit prices for the carrots at both stores and then we will discuss what you did. Have students independently calculate the unit price and answer which store has the better deal. Compare how different students did the calculations, and have students discuss similarities and differences among the models they used and solutions they found.

Which animal runs faster? Developing the Concept: Rates Now that students know how to find a unit rate, they will learn how to find an equivalent ratio using unit rates. Now we are going to learn how to use that unit rate to solve problems.

Look at this problem. If she runs at that rate for 30 laps, how long will it take her? Ask: What are we trying to find in this problem? We are trying to find out how long it takes Ebony to run 30 laps. Ask: What information do we know that will help us solve this problem?

We know that Ebony can run 18 laps in 12 minutes. We also know she is going to run at that same rate for 30 laps. Ask: How far does Ebony run in one minute? Have students try to figure it out individually.

Compare student solutions, and discuss why Ebony runs 1. What is the difference between ratios and rates? Becca M. Dec 8, Both rates and ratios are a comparison of two numbers.
