Background Tutorials

Understand the concept of a ratio and use ratio language to describe a ratio relationship between two quantities.

Ratios are everywhere! The scale on a map or blueprint is a ratio. Ingredients sometimes need to be mixed using ratios such as the ratio of water to cement mix when making cement. Watch this tutorial to learn about ratios. Then think of some ratios you've encountered before!
