    Chapter 17. Ratio, Proportion, and Variation

    OBJECTIVES

    When you have completed this chapter, you should be able to

    • Set up and solve a proportion for a missing quantity.

    • Solve applied problems using proportions.

    • Find dimensions, areas, and volumes of similar geometric figures.

    • Set up and solve problems involving direct variation, inverse variation, joint variation, and combined variation.

    • Solve applied problems involving variation.

    • Set up and solve power function problems.


    We earlier described a ratio as the quotient of two quantities, say a/b. Here we will set one ratio equal to another to get a proportion. We will learn how to solve proportions for a missing quantity.
