Description Reviewing Representations of Ratios

After this lesson you will be able to apply your knowledge of ratios to many real world scenarios.

The video begins with a review of ratio notation and how to find unit rate. It continues with how to use ratio tables and tape diagrams to find equivalent and associated ratios. It concludes with a review of ratios in graphs, and finding the constant of proportionality.

This video includes key concepts, notation, and vocabulary such as: ratio (a comparative, proportional relationship between two amounts); equivalent ratios (two ratios which represent the same proportional relationship); tape diagrams (a diagram used to visualize a set of equivalent ratios); ratio tables (a table of equivalent ratios); unit rate (a proportional relationship which compares a quantity to one unit of another quantity).

Before watching this video, you should already be familiar with writing ratios, simplifying ratios, tape diagrams, ratio tables, and plotting ratios on a coordinate plane.

After watching this video, you will be prepared to learn more about rates, unit rates, and solve real world rate problems.
