1 Setting up and Solving Proportional Equations Sunday, November 01, 2015 We are learning to…solve problems that involve proportional reasoning.

2 What is a proportion? Proportion – two ratios (comparisons) that are equal. Example:  Charlie makes 5 phone calls in 2 days. How many phone calls will he make in 12 days? Table:Proportion: CallsDays 52 x12

3 Use your equation solving skills to find the solution of the proportion below. (12) Charlie will make 30 phone calls in 12 days

4 Practice Problem #1 A pipe leaks 7 quarts of water in 6 hours. At this rate how much water will the pipe leak in 10 hours? Table: Proportion:Solution: QuartsHours 76 X10 (10) The pipe will leak 11 and 2 / 3 quarts of water in 10 hours.

5 Practice Problem #2 Xavier sends 52 text messages in 4 days. At this rate how many text messages will he send in 7 days? Table: Proportion:Solution: TextsDays 524 X7 (7) Xavier will send 91 text messages in 7 days.
