ratio

比 比率

Ra·ti·o n.

1. Math. The relation which one quantity or magnitude has to another of the same kind. It is expressed by the quotient of the division of the first by the second; thus, the ratio of 3 to 6 is expressed by *a* to *b* by a/b; or (less commonly) the second term is made the dividend; as, a:b = b/a.

Note: ☞ Some writers consider __ratio__ as the quotient itself, making ratio equivalent to a number.

The term __ratio__ is also sometimes applied to the __difference__ of two quantities as well as to their __quotient__, in which case the former is called __arithmetical ratio__, the latter, __geometrical ratio__. The name __ratio__ is sometimes given to the __rule of three__ in arithmetic. See under Rule.

2. Hence, fixed relation of number, quantity, or degree; rate; proportion; as, the ratio of representation in Congress.

**Compound ratio**, **Duplicate ratio**, **Inverse ratio**, etc. See under Compound, Duplicate, etc.

**Ratio of a geometrical progression**, the constant quantity by which each term is multiplied to produce the succeeding one.
