Vocabulary A rate is a ratio that compares two quantities measured in different units. The unit rate is the rate for one unit of a given quantity. Unit rates have a denominator of 1.

Rate Examples (more than 1) 250 words in 5 minutes 92 pages read in 8 minutes 225 miles in 5 hours $3.25 for 5 bananas

Unit Rate Examples (only 1) 50 words per minute 11.5 pages per minute 45 miles per hour $0.65/banana

Example #1 Rate: 150 heartbeats 2 minutes Find Unit Rate (Divide to get it): 150 ÷ 2 = 75 heartbeats per minute.

REMEMBER ONCE YOU HAVE A UNIT RATE YOU WILL BE ABLE TO MULTIPLY BY ANY NUMBER TO FIND ANOTHER VALUE. EXAMPLE 50 WORDS PER MINUTE YOU CAN TYPE. HOW MANY WORDS CAN YOU TYPE IN 6 MINUTES…… 50 X 6 = 300

Example #2 Amy can read 88 pages in 4 hours. What is the unit rate? 88 pages 4 hours 22 pages / hour 1)What was the rate that was given in the question? 2)What is the UNIT RATE?

Example #3 Marlo divided 40.8 gallons of paint among 8 containers. How much paint is in each container? Rate: Unit Rate:

Comparing Unit Prices

Example #4 The Reyes family bought four tickets for $252. What was the price per ticket?

Example #5 Juice is sold in one size. A 28-fluid ounce bottle costs $2.24. $ fl.oz $.08 per fl.oz.

Practice Time 1)Put your name on a sheet of paper. 2)Number )SKIP A FEW LINES IN BETWEEN EACH NUMBER—you will need to show your work. Ex. Rate: Unit Rate:
