  1. Dividing Fractions Using word ProblemsAbsent Copy1/22,23

  2. Example 1 • A can of soup contains 3½ cups of soup. The suggested serving size is ¼ cup. How many servings are in the can of soup? 3½ ÷ ¼ 7 • 4 2 1 7 • 4 = 28 2 • 1 2 14 Solution • What operation do you think we will use in this problem? • We will use Division to solve this problem. • What do we do with the mixed #? • Change it into a fraction. • What do we do next? • Use KFC and re-write the equation. • What is our next step? • We multiply the fractions. • Can we reduce the answer? • YES 14 servings of soup

  3. Example 2 • A flip flop manufacturer uses of a yard of material for each flip flop. How many flip flops can be made from 8 yards of material? 8 ÷ 7 8 35 ÷ 7 4 8 35 · 8 = 264 4 7 28 280 28 2 · 2 · 2 · 7 · 5 2 · 2 · 7 2 · 2 · 2 · 7 · 5 2 · 2 · 7 10 Solution • What operation do you think we will use in this problem? • We will use Division to solve this problem. • What do we do with the mixed #? • Change it into a fraction. • What do we do next? • Use KFC and re-write the equation. • What is our next step? • We multiply the fractions. • Can we reduce the answer? • YES by making a T-chart. 10 flip flops

  4. Example 3When you take the quotient of 3 ÷ why is the solution going to be greater than 3? The reason why your solution is greater is because you are trying to see how many little ¼ groupings can fit into 3 wholes. Of course you can fit more than three ¼’s into 3 wholes.
