A: Rational Expressions: Applications
Module by: Wade Ellis, Denny Burzynski. [ E-mail the authors
Summary:
This module is from Elementary Algebra by Denny Burzynski and Wade Ellis, Jr.
A detailed study of arithmetic operations with rational expressions is presented in this chapter, beginning with the definition of a rational expression and then proceeding immediately

to a discussion of the domain. The process of reducing a rational expression and illustrations of multiplying, dividing, adding, and subtracting rational expressions are also included. Since the operations of addition and subtraction can cause the most difficulty, they are given particular attention. We have tried to make the written explanation of the examples clearer by using a "freeze frame" approach, which walks the student through the operation step by step.
The five-step method of solving applied problems is included in this chapter to show the problem-solving approach to number problems, work problems, and geometry problems. The chapter also illustrates simplification of complex rational expressions, using the combine-divide method and the LCD-multiply-divide method.
Objectives of this module: be able to use the five-step method to solve various applied problems.
Overview
The Five-Step Method
The Five-Step MethodWe are now in a position to study some applications of rational equations. Some of these problems will have practical applications while others are intended as logic developers.We will apply the five-step method for solving word problems.
Five-Step Method
Represent all unknown quantities in terms of x
or some other letter. Translate the verbal phrases to mathematical symbols and form an equation. Solve this equation. Check the solution by substituting the result into the original statement of the problem. Write the conclusion. ]
