1. Solving Ratio Problems With Tables, Tape Diagrams & Double Number Lines
In this lesson, you'll find out how to solve ratio problems in three different ways. For example, you'll learn how to use a table, a tape diagram and a double number line while deciding which method for solving a ratio problem is right for you.
2. Equivalent Ratios: Definition & Examples
In this lesson, you'll learn what ratios are and discover their relationship with fractions. You'll also learn what makes ratios equivalent and look at some examples.
3. How to Solve a Rational Equation
A rational equation is one that contains fractions. Yes, we will be finding a common denominator that has 'x's. But no worries! Together we will use a process that will help us solve rational equations every time!
4. Ordered Pairs on the Coordinate Plane
In this video lesson, you will see how points are plotted on the coordinate plane. Learn the proper way to identify points on the coordinate plane and how to read the points.
5. How to Calculate Unit Rates & Unit Prices
One of the most common uses of math is to find out whether something is a 'good deal.' Unit prices, a special kind of unit rate, allow us to determine the best deals. In this lesson, learn how to calculate unit rates, including unit prices.
6. Solve Problems Using Percents
Percents are your friend. Think of all the cool things percents do for you. They save you money, and they tell you how well you are doing in school. Learn how you can solve problems with percents in this video lesson.
