Ratios & Rates: Definitions & Examples

1. Ratios & Rates: Definitions & Examples

In mathematics, a ratio indicates the number of times that a smaller number is contained within a larger number, while a rate expresses a ratio for two quantities measured in different units. Explore the definitions and examples of ratios and rates, learn how to compare them, and solve practice problems.

Proportion: Definition, Application & Examples

2. Proportion: Definition, Application & Examples

A problem with a proportion, which is a set of ratios that equal each other, can be solved with cross-multiplication. Learn about proportions, see sample problems, and learn how to calculate percent problems.

Calculations with Ratios and Proportions

3. Calculations with Ratios and Proportions

Ratios allow us a way to mathematically compare two or more items, and proportions can help us find out even more information. Learn the definition of ratios and proportions, and understand how to calculate ratio and proportion problems.

Solving Problems Involving Proportions: Definition and Examples

4. Solving Problems Involving Proportions: Definition and Examples

Proportion equations are an excellent solution to determine missing sides or to increase/decrease the size of an object. Learn about the definition of proportions, see examples of proportions, and learn how to solve proportional equations to find the length of a missing side.

Slopes and Rate of Change

5. Slopes and Rate of Change

The rate of change is shown through one variable as it changes the function of another variable and can be seen furthermore as location changes as a function of time. Learn more about slopes, rates of change, and the rate of velocity.

Solving Equations of Direct Variation

6. Solving Equations of Direct Variation

Direct variation problems involve two variables that vary directly with each other, which means, for example, as one increases, so does the other. Learn the formula for solving equations of direct variation, and practice with example problems.
