DeSoto Co. Schools 7th Grade Math 7.RP.1 Unit Rates / Unit Cost

Unit ONE 1:Uno Study this slide for a moment. In your own mind, can you figure out what the word UNIT means? DON’T holler out the answer!

Unit Rate Let’s take a look at Unit Rate first.

Unit Rate It is the rate for “1” unit of something. Example: If you drive miles in hours, how far did you drive in 1 hour? STEP 1 Write the problem as a ratio in fraction form. STEP 2 Divide to get your answer!

A trip to “florida” _ ?_ mi. in 1 hr. Traveling mi. in hrs. If you travel 750 3/4 miles in 10 1/2 hours… How many miles do you travel in 1 hour? (750 ¾)/ (10 1/2)= 71 1/2miles in one hour

Mississippi state basketball Scoring 96 points in games. _ ?_ points in 1 game. If this Mississippi State dude scored 96 points in 6 1/2 games… how many points did he score in 1 game? 96/ 6 1/2 = 14 10/13 points per game

Measuring your heart rate heartbeats in minutes. _ ?_ heartbeats in 1 minute. If your heart beats 17 1/2 beats in 1/4 minutes… How many times does it beat in 1 minute? (17 ½)/(1/4) = 70 beats per minute

Reading your favorite book Reading pages in hours. _ ?_ pages in 1 hour. You Try! You read 19 1/2 pages in 3/4 hours… how many pages do you read in 1 hour? (19 ½)/(3/4) = 26 pages per hour You Try!

In closing….. Karen ran 0.5 mile in minutes. Marcus ran miles in minutes. Amy said that Marcus had the fastest time. Is she correct? Explain your reasoning.
