- a:b means a/b.
- a is antecedent and b is consequent.

- Duplicate ratio of a:b is a²:b².
- Triplicate ratio of a:b is a³:b³.
- Four quantities are in proportion when the first-second ratio equals the third-fourth ratio.
- a and d are extremes.

The order of terms in a ratio does not matter.
A ratio has units because the original quantities have units.
