Fraction Operations


This chapter builds on the fraction theory presented in Chapter 4 by applying the four basic operations to fractions and mixed numbers. Multiple operations are brought together in a discussion of rational expressions, and the chapter closes with a presentation of equivalent algebraic expressions involving fractions.
