Improper fractions are fractions that their numerators are larger than or equal to their denominators. On the other hand, mixed numbers, also known as compound fractions, are numbers that have both a whole number and a fraction. In this section, a model will be used as a way to multiply mixed numbers and improper fractions. We will also practice questions of multiplying improper fractions and mixed numbers algebraically.

Basic Concepts: Determining Common Factors, Determining common multiples, Multiplying proper fractions

Related Concepts: Comparing and ordering rational numbers, Solving problems with rational numbers in fraction form, Solving two-step linear equations: $ax + b = c$, ${x \over a} + b = c$
