Closed Captioned Video: Ratios: Ratios with Three Items

Topic

Ratios

Description

The video explains ratios involving more than two items, such as 1:3:4, and how they encompass multiple pairwise ratios. Applications include recipes where ingredients are combined in specific proportions. It demonstrates working forward and backward with ratios to identify components or adjust quantities proportionally.

This video explains the concept of ratios by The video explains ratios involving more than two items, such as 1:3:4, and how they encompass multiple pairwise ratios.

What Are Ratios?

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

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.

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

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