1. How to Solve Ratio Word Problems
Ratios are everywhere. They are just a way to compare two numbers. Learn what ratios are, how they can be used to create a proportion, and how to use them to solve a word problem.

2. Solving Ratio Problems Involving Totals
Ratio problems may involve comparing two amounts to find a total. Learn about ratios and the steps for solving problems with totals by utilizing proportions and cross multiplication.

3. Ideal Gas Law Ratios
The Ideal Gas Law is used primarily in chemistry. The formula is PV = nRT. We can use this in solving problems involving gases and solve the equation for any of the variables to find our unknown.

4. Applying Scale Factors to Perimeter, Area, and Volume of Similar Figures
A scale factor is a number that shows the relationship between the corresponding perimeter, area, and volume of similar figures. Learn about the scale factor along with examples of how it is applied to perimeter, area, and volume.

5. How to Use Proportions With Chemical Compounds
Much of chemistry deals with the proportions of elements in chemical compounds. In this lesson, we will investigate characteristics of these proportions and go through some applications of these proportions.
