- n. The relation between two similar magnitudes in respect to quantity; the relation between two similar quantities in respect to how many times one makes so many times the other. There is no intelligible difference between a ratio and a quotient of similar quantities: they are simply two modes of expression connected with different associations. But it was contrary to the old usage to speak of a ratio as a quantity—a usage leading to intolerable complications. Thus, instead of saying that the momentum of a moving particle is the product of its mass into its velocity—a mode of expression both convenient and philosophical—the older writers say that the momenta of two particles are in the compound ratio of their masses and velocities. This language, which betrays several errors of logic, is now disused; although some writers still persist in making numbers the only subjects of addition and multiplication. By mathematicians ratio is now conceived and spoken of as synonymous with quotient.
- n. Proportion of relations or conditions; coincident agreement or variation; correspondence in rate; equivalence of relative movement or change.

- n. Loosely, a direct and simple ratio: as, the weights of bodies are in the direct ratio of their masses—that is, the weight of one is to that of another as the mass of the former is to that of the latter. Also direct proportion
- n. See progression.
- n. A ratio not compound.
- n. A number representing a comparison between two things.
- n. arithmetic The relative magnitudes of two quantities (usually expressed as a quotient).
- n. law Short for ratio decidendi.
GNU Webster's 1913
- n. (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 3/6 or 1/2; of a to b by a/b; or (less commonly) the second term is made the dividend; as, a:b = b/a.
- n. Hence, fixed relation of number, quantity, or degree; rate; proportion.
- n. the relation between things (or parts of things) with respect to their comparative quantity, magnitude, or degree
- n. the relative magnitudes of two quantities (usually expressed as a quotient)
