Ratios & Proportions
A ratio describes a multiplicative relationship or repeatable batch, and proportional situations preserve that relationship as quantities scale.
What you'll learn
- Distinguish part-to-part from part-to-whole comparisons.
- Interpret a ratio as a repeatable batch.
- Scale corresponding quantities by the same factor.
- Recognize and complete proportional relationships without relying on cross-multiplication as a starting rule.
