Lesson Plan

Description:

The lesson begins with using the lcd to clear the fractions in the equation, and then a review of proportions follows to motivate the "shortcut" of cross multiplication for equations containing only a fraction on each side of the equation. The possible existence of extraneous solutions and solving the equations graphically is discussed before application problems are presented. The lesson concludes with exercises in manipulating formulas.
