### About This Chapter

## FTCE Math: Ratios & Proportions - Chapter Summary

Prepare to show how much you know about ratios and proportions on exam day. Use the targeted video lessons and quizzes to review these topics for the FTCE Math exam. You'll find lessons on:

- Ratios and rates
- Methods for finding constant and average rates
- Problems with proportions
- Calculations involving ratios and proportions
- Proportional relationships
- Average rate of change
- Problems with direct and inverse variation

This chapter is designed to help you review what you need to know about ratios and proportions. Your progress is tracked from the dashboard, so you won't miss a lesson. These resources cater to different learning styles and include both videos and written transcripts. This double-format approach enhances your learning process and helps you retain information more effectively for the FTCE Math exam.

### 1. Ratios & Rates: Definitions & Examples

If we have two items, or two numbers, and we want to compare them, what language can we use? How do we write the comparison? Find out as we learn about ratios and rates in this lesson.

### 2. Finding Constant and Average Rates

Watch this video lesson to learn the differences between constant and average rates. You will learn the steps you need to take to find them and get two great visuals you can keep in mind to help you solve these rate problems.

### 3. Proportion: Definition, Application & Examples

When we want to compare one ratio, or fraction, to another equivalent ratio, it's a proportion. Learn all about proportions and practice solving proportion problems in this lesson.

### 4. Solving Problems Involving Proportions: Definition and Examples

Learn how you can use proportions to find missing sides and how to increase or decrease the sizes of objects to create models of them in this video lesson.

### 5. Calculations with Ratios and Proportions

Even if only 99 out of 100 people need to know how to work with ratios, the odds that they'll be useful to you are very high. In this lesson, we'll practice performing calculations with ratios and proportions.

### 6. Proportional Relationships Between Two Quantities

When two values always maintain the same ratio, forming the same fraction when you divide them, they have a proportional relationship. In this lesson, you can learn about proportional relationships between two quantities.

### 7. Average Rate of Change: Definition, Formula & Examples

Average rate of change and slope of a line are very interconnected. They are actually one in the same. In this lesson, we will be discovering how they are interconnected.

### 8. Direct and Inverse Variation Problems: Definition & Examples

In this lesson, you'll learn how to approach questions about direct and inverse variation with a simple explanation of what the terms mean and how to apply them to problems.
