This booklet explains how to use ratios to make unit conversions. It includes explanations of what a ratio is and instructions on how to set up a ratio. There are simple examples showing how to convert different measurements (example: quart to cup) along with more complex conversions such as how many 7.5" pencils fit end to end down a 20' hallway. The ratios are set up in fraction-form for each equation.

This booklet is intended for students just learning how to use ratios to make conversions.

There are two versions of the book, black-and-white and color, along with simple assembly directions. The book has 3 pages, double-sided, folded in half and stapled.
