How many square feet does Angela paint per hour? area painted = 55 sq. ft hrs. ÷ · = 110 sq. ft/hr • How do we set up a ratio for this problem? • We set it up as sq. ft divided by hrs. • What division symbol do we use so that we can solve the problem? • We use the ÷ symbol • After re-writing the fractions with the proper division symbol what is the next step in solving the problem? • We KFC the division problem • How many square feet can she paint per hour? • She paints 110 sq. ft per hour

  3. Example 2 • Find the unit rate. Paul walks 4 miles in 1 hrs. What is the unit rate of how far he walks in 1 hr? ________ ÷ · = = 2 • How do we set up a ratio for this problem? • We set it up as miles walked divided by hrs. • What division symbol do we use so that we can solve the problem? • We use the ÷symbol • After re-writing the fractions with the proper division symbol what is the next step in solving the problem? • We KFC the division problem • How many miles did he walk in 1 hour? • He walked 2 5/6 miles

  4. Example 3 • Ingredient A requires cups for servings and ingredient B: requires cups for servings. Which ingredient has the lower unit rate? • Ingredient AIngredient B _______ _______ ÷÷ · =· = • How do we set up a ratio for this problem? • We set it up as cups divided by servings. • What division symbol do we use so that we can solve the problem? • We use the ÷symbol • After re-writing the fractions with the proper division symbol what is the next step in solving the problem? • We KFC the division problem • Which ingredient has the lower unit rate per serving? • Ingredient B
