# Ch 5: SBA Math - Grade 8: Operations with Fractions

### About This Chapter

## SBA Math - Grade 8: Operations with Fractions - Chapter Summary

This chapter covers how to deal with complex fractions as well as less complicated operations, such as addition and subtraction with like fractions. Other fraction topics in the chapter of varying difficulty that help 8th grade students prepare for SBA Math assessment items include:

- Multiplication and division with fractions and mixed numbers
- Determining the unknowns in a proportion
- Subtracting and adding unlike fractions and mixed numbers
- Basic operations with decimal notation

At any time throughout the duration of a video lesson, a student can use the video tags to quickly return to a certain part to double-check anything. Students are able to establish their level of comfort with the material by taking each lesson's practice quiz.

### SBA Math - Grade 8: Operations with Fractions Chapter Objectives

The SBA Math assessments for students in 8th grade inform teachers and schools of how much a student has advanced in the subject across a school year. SBA Math assessments feature multiple-choice, computer-adaptive questions for the most part. Students may come across assessment items that resemble some of the practice questions in this chapter.

### 1. 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.

### 2. 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.

### 3. 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.

### 4. 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.

### 5. How to Solve Complex Fractions

Did you know fractions can nest within fractions? In this lesson, we'll learn about complex fractions and look at two different methods for solving them.

### 6. Addition, Subtraction, Multiplication, and Division with Decimal Notation

Performing operations such as addition, subtraction, multiplication and division has some differences when there are decimals involved. This lesson will explain how to perform these operations all while keeping the decimals straight.

### 7. Practice with Fraction and Mixed Number Arithmetic

Adding whole numbers is one thing. But adding fractions and mixed numbers? That's not so simple. Or is it? In this lesson, we'll practice arithmetic with both fractions and mixed numbers.

### 8. Estimation Problems using Fractions

When working with fractions, estimating can save time and effort while getting you very close to the correct answer. In this lesson, we'll learn how to use estimation to quickly solve problems involving fractions.

### 9. How to Find an Unknown in a Proportion

Artists, engineers, athletes, and accountants all use proportions in their daily lives, and setting them up is really quite easy, once you know the rules. In this lesson, you'll learn how to solve proportions when there is an unknown value and work on some practice problems.

### 10. Solving Problems using Fractions and Mixed Numbers

Fractions don't just live in math problems. They're all around us, helping us through our lives. In this lesson, we'll look at real scenarios where your ability to work with fractions can save the day.
