Check Your Understanding 1. Make use of structure. Sometimes the denominator of one fraction or one rational expression works as a common denominator for all fractions or rational expressions in a set. a. Write two fractions (rational numbers) in which the denominator of one of the fractions is a common denominator. b. Write two rational expressions in which the denominator of one of the expressions is a common denominator. c. Show how to add the two rational expressions you wrote in Part (b). 2. List the steps you usually use to add or subtract rational expressions with unlike denominators.

Model with mathematics. In the past week, Emilio jogged for a total of 7 miles and biked for a total of 7 miles. He biked at a rate that was twice as fast as his jogging rate. a. Suppose Emilio jogs at a rate of r miles per hour. Write an expression that represents the amount of time he jogged last week and an expression that represents the amount of time he biked last week. Hint: distance = rate × time, so time = distance . rate b. Write and simplify an expression for the total amount of time Emilio jogged and biked last week. c. Emilio jogged at a rate of 5 miles per hour. What was the total amount of time Emilio jogged and biked last week? 9.
