Overview

This chapter builds the skills needed to perform basic arithmetic with fractions. Numerical factoring, multiples, divisibility, and prime numbers are reviewed and then used to find greatest common factors and least common multiples.  These skills are applied to renaming fractions. The chapter ends with a discussion of rational numbers.
