Ratio and Unit Rates

  1. 1. Ratio, Rate & Unit Rate <ul><li>Rate or ratio – a comparison of two items Ex. The ratio of smiley-faces to hearts is: </li></ul><ul><li>2) Unit rate or cost – when one of the numbers equals 1 Ex. 2:1 </li></ul>
  2. 2. Ex 1: Find the unit rate or unit price. A) B) = 25 mi/hour = $.60/can
  3. 3. Find the total amount using the unit rate. <ul><li>$5.25 per hour for 7 hours </li></ul><ul><li>$6.32 per hour for 5 hours </li></ul>5.25 x 7 = $36.75 6.32 x 5 = $31.60
  4. 4. Ex 2: Find the unit rate, then solve. A) A 2 lb. package of candy costs $3.98; a 3 lb. package costs $5.67. Which is a better buy? $1.89/lb. is cheaper than $1.99/lb., so the 3 lb. package is a better buy.
