Dividing fractions and mixed numbers
In this section, we will use diagrams to divide fractions and mixed numbers (a.k.a. compound fractions) for the purpose of helping you getting a better understanding about the concepts of fraction division. We will also teach you how to divide fractions by using multiplications.
Basic Concepts: Determining Common Factors, Determining common multiples, Multiplying improper fractions and mixed numbers
Related Concepts: Comparing and ordering rational numbers, Solving problems with rational numbers in fraction form, Solving two-step linear equations: ax+b=c, ax+b=c
