Webster's 1913 Dictionary
\Ra"ti*o\, n. [L., fr. reri, ratus, to reckon, believe,
think, judge. See {Reason}.]
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 3/6 or 1/2; of a to b
   by a/b; or (less commonly) the second 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

{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
