1. How to Solve Ratio Word Problems

We see ratios all around us every day. From the grocery store, to forecasting into the future, to enlarging or shrinking pictures, a command of ratios can be a powerful math tool. In this lesson, learn how to solve word problems with ratios in them.

2. Solving Ratio Problems Involving Totals

A brief review of what ratios are will be given, and then we will look at ratio problems involving totals. We will look at the steps involved in solving these types of problems using various examples.

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

How do shapes change sizes yet retain their proportions and similarities to other shapes? In this lesson, we'll look at what a scale factor is and how to apply it. We'll consider scale factors with regards to three different aspects of similar shapes: 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.
