4-2 Unit Rates and Proportional Reasoning A rate is a ratio that compares two quantities measured in different units. Example: There are 15 grams of fat in 5 servings of canned soup. 15 grams of fat 5 servings

The rate for one unit of a given quantity is the unit rate. Ex: 15 grams of fat 5 servings To find a unit rate, divide the first quantity by the second quantity. 15 ÷ 5 = 3 grams of fat per serving

Example (I do) A package of cheddar cheese contains 15 servings and has a total of 147 grams of fat. Find the unit rate of grams of fat per serving. 147 grams 15 servings 147 grams ÷ 15 servings = 9.8 A package of cheddar cheese 9.8 grams of fat per serving

Example (we do) Find the unit rate for 210 heartbeats in 3 minutes 210 heartbeats 3 minutes 210 heartbeats ÷ 3 minutes = 70 The unit rate is 70 beats per minute

A unit rate that gives the cost per unit is a unit cost. To find a unit cost of an item, divide the total cost of an item by the number of units in the item.

Example (I do) Two sizes of shampoo bottles are shown. Which size is the better buy? $ fl. oz $6.19$ oz oz. $ fl. oz ≈ $.30/fl oz. ≈ $.39/fl oz. Since $.30 < $.39. the 13.5 fl oz bottle is the better buy.

Example (we do) Which bottle of apple juice is the better buy? $ fl. oz $3.19$ oz. 12 oz. $ fl. oz ≈ $.25/fl oz. ≈ $.16/fl oz. Since $.16 < $.25 the 20 oz bottle is the better buy.

Whiteboard Time! Find the unit rate: You earn $33 for 4 hours of work $33 4 hrs 33 ÷ 4 = $8.25/hr

Whiteboard Time! Find the unit rate: James Harden signed a 5 year / $78,782,188 contract. How much does he make per year. $78,782,188 5 yrs 78,782,188 ÷ 5 = $15,756,437/yr

Whiteboard Time! Odell Beckham catches 12 passes for 186 yards on Sunday. How many yards per reception did he have? 186 yards 12 catches 186 ÷ 12 = 15.5 yds per reception

Whiteboard Time! A 6 pack of 5 Hour Energy costs $8.99. A 12 pack costs $ Which is the better buy? $ bottles $ bottles ≈ $1.04/bottle ≈ $1.50/bottle Since $1.04 < $1.50 the 12 pack is the better buy.
