Synopsis
Foundations of ratio and proportion for early algebra learners
This volume presents the core ideas of ratio, proportion, and their manipulation. It explains how ratios relate to fractions, how compound ratios are built from simple ones, and how changing one term affects the whole comparison.

- Learn the meaning of ratio and how it connects to fractions and proportions
- Understand direct and reciprocal ratios, and how to transfer factors between terms
