is a kind of magnitude relation, quantitative relation
1. 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
2. Hence, fixed relation of number, quantity, or degree; rate; proportion; as, the ratio of representation in Congress. [1913 Webster]
ratio, n. (pl. -os) the quantitative relation between two similar magnitudes determined by the number of times one contains the other integrally or fractionally (in the ratio of three to two; the ratios 1:5 and 20:100 are the same).
