5. (Math.) (a) The equality or similarity of ratios, especially of geometrical ratios; or a relation among
quantities such that the quotient of the first divided by the second is equal to that of the third divided by
the fourth; — called also geometrical proportion, in distinction from arithmetical proportion, or that in
which the difference of the first and second is equal to the difference of the third and fourth.
Proportion in the mathematical sense differs from ratio. Ratio is the relation of two quantities of the
same kind, as the ratio of 5 to 10, or the ratio of 8 to 16. Proportion is the sameness or likeness of two
such relations. Thus, 5 to 10 as 8 to 16; that is, 5 bears the same relation to 10 as 8 does to 16. Hence,
such numbers are said to be in proportion. Proportion is expressed by symbols thus:
a:b::c:d, or a:b = c:d, or a/b = c/d.
