# Ch 2: OAE Mathematics: Fractions

### About This Chapter

## OAE Mathematics: Fractions - Chapter Summary

Use this chapter to get extra practice working with improper, mixed number, like and unlike fractions. Our lessons are designed to prepare you for OAE Mathematics questions testing your ability to do the following:

- Build and reduce fractions
- Find the least common denominator
- Convert between improper and mixed number fractions
- Perform arithmetic operations with fractions

This chapter's video lessons, transcripts and multiple-choice quizzes can be used in any combination to review OAE exam topics. Moreover, these self-paced resources are available to you wherever you take your laptop, tablet or smartphone.

### OAE Mathematics: Fractions Chapter Objectives

Lessons in this chapter can help you sharpen the problem-solving skills you'll need to answer test questions involving rational numbers. These types of problems are included in the mathematical processes and number sense content domain, one of five main test areas used to determine your preparedness for a math teaching license in Ohio.

### 1. How to Build and Reduce Fractions

Fractions are a fundamental part of everyday life. Fractions represent a comparison of a part to the whole. To reduce fractions, we will divide by the greatest common factor, or the GCF.

### 2. How to Find Least Common Denominators

Finding a Least Common Denominator is an important tool when working with fractions. To find least common denominators, we will use multiples of our numbers.

### 3. Changing Between Improper Fraction and Mixed Number Form

Improper fractions and mixed numbers are two different types of fractions. They both have different purposes when using fractions in a problem. In this lesson, you will learn how to convert between these two different forms.

### 4. How to Add and Subtract Like Fractions and Mixed Numbers

When adding and subtracting fractions, you must be sure to have a common denominator. Once you have a common denominator, you just add or subtract your numerators and then your whole numbers. Learn how in this lesson.

### 5. How to Add and Subtract Unlike Fractions and Mixed Numbers

Simple fraction arithmetic gets a little more complicated when our denominators don't match. In this lesson, we'll learn how to add and subtract unlike fractions. Then, we'll do the same with mixed numbers.

### 6. Multiplying Fractions and Mixed Numbers

Multiplying fractions is much more straightforward than adding, subtracting or dividing fractions. In this lesson, learn how it works. We'll also learn how to multiply mixed numbers.

### 7. Dividing Fractions and Mixed Numbers

Dividing fractions and mixed numbers? It sounds daunting, but it's not as tricky as it sounds. In this lesson, we'll learn how to divide fractions and mixed numbers.
