| Summary |
 |
Ratio is the numerical relationship between two quantities of the same kind. The first quantity is called the antecedent and the second quantity is called the consequent. |
| |
By performing simple operations on ratios, we get compounded ratio, duplicate ratio, triplicate ratio, sub-duplicate ratio and sub-triplicate ratio. |
| |
If two ratios are equal, we get four quantities in proportion. |
| |
If three quantities are in continued proportion, the second quantity is called the mean proportion. |
| |
Important results in proportions are: Invertendo, Alternendo, Componendo, Dividendo and Componendo and Dividendo. |
