Video Transcript: Ratios: Rates

Video Transcript: Ratios: Rates

What Are Ratios?

A ratio is the relationship between two or more quantities among a group of items. Let's look at an example.

An example of the ratio of groups of coins.

Here is a collection of coins. The ratio of pennies to dimes can be expressed as a ratio, and a ratio can be written in three different, but equivalent ways.

 

When expressed as fractions, ratios can then be rewritten as fractions in simplest form.

An example of the ratio of groups of coins.

For some groupings, you can write a ratio that includes three terms.

An example of the ratio of groups of coins.

Ratios usually include similar types of objects. Here is a collection of different types of balls.

An example of the ratio of groups of balls.

Rates are a special type of ratio. Rates involve different types of quantities. Here is an example of a rate involving cost and weight. 

An example of a rate.
