Dividing Fractions Using word Problems Absent Copy 1/22,23

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? 3 ½ ÷ ¼ = 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

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 ÷ ÷ · 8 = · 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

Example 3 When 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.
