This is a short review page that covers: unit cost, equivalent ratios, rate tables, cross-products, scale, scale factor, and similar figures.
It includes an answer key, and plenty of room to show work.
Here are other projects I have about ratios and proportions:
Unit Rate Maze
Unit Prices Maze: Which Product is the Better Buy?
Scaffolded Notes on Ratios, Unit Rates, and Unit Prices
Unit Rate, Unit Price, and Ratio Tables Practice Problems
