About This Chapter
Ratios and Proportion - Chapter Summary
Our instructors teach your student about ratios, proportions and rates as well as how they compare. Instructions for how to find the unit rate of change and solve one-step problems involving ratios are included in this chapter. Your student can also see examples of proportions and understand the steps for perform calculations with them. Once this chapter is complete, your student should be able to do the following:
- Give examples of ratios and rates
- Find a unit rate of change
- Quickly solve one-step ratio problems
- Use proportions to compare ratios
- Make calculations using ratios and proportions
- Understand how to use proportions when solving real-world problems
Our learning materials are all mobile friendly and accessible on a tablet, mobile phone or computer at any time, 24 hours a day. When reviewing this chapter, feel free to contact one of our instructors if your student has any difficulty. If your student would like to watch just one portion of one of our video lessons, use the video tabs feature to jump directly to that section. The quizzes that follow each lesson are a great way to measure how well your student understands what he or she is learning.
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. How to Find the Unit Rate
If we are going to use math to predict outcomes, one of the most useful measures we can establish is the unit rate of change. In this lesson, you'll learn how to find the rate of change and apply the formula to real-life examples.
3. How to Solve a One-Step Problem Involving Ratios
Ratios show the relationship between different things. They can be very useful in math and everyday life. Learn how you can quickly and easily solve one-step ratio problems.
4. 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.
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. Constructing Proportions to Solve Real World Problems
In this lesson, we will concentrate on proportions. Through definition and example, we will learn how to construct proportions and how to use proportions to solve real world problems.
