\Pro*por"tion\, n. [F., fr. L. proportio; pro before + portio part or share. See {Portion}.]
1. The relation or adaptation of one portion to another, or to the whole, as respect magnitude, quantity, or degree; comparative relation; ratio; as, the proportion of the parts of a building, or of the body. The image of Christ, made after his own proportion. --Ridley. Formed in the best proportions of her sex. --Sir W. Scott. Documents are authentic and facts are true precisely in proportion to the support which they afford to his theory. --Macaulay.
2. Harmonic relation between parts, or between different things of the same kind; symmetrical arrangement or adjustment; symmetry; as, to be out of proportion. ``Let us prophesy according to the proportion of faith.'' --Rom. xii.
6.
3. The portion one receives when a whole is distributed by a rule or principle; equal or proper share; lot. Let the women . . . do the same things in their proportions and capacities. --Jer. Taylor.
4. A part considered comparatively; a share.
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. Note: 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 1
6. 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 1
6. 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. (b) The rule of three, in arithmetic, in which the three given terms, together with the one sought, are proportional. {Continued proportion}, {Inverse proportion}, etc. See under {Continued}, {Inverse}, etc. {Harmonical, or Musical}, {proportion}, a relation of three or four quantities, such that the first is to the last as the difference between the first two is to the difference between the last two; thus, 2, 3, 6, are in harmonical proportion; for 2 is to 6 as 1 to
3. Thus, 24, 16, 12, 9, are harmonical, for 24:9::8:
3. {In proportion}, according as; to the degree that. ``In proportion as they are metaphysically true, they are morally and politically false.'' --Burke.
\Pro*por"tion\, v. t. [imp. & p. p. {Proportioned}; p. pr. & vb. n. {Proportioning}.] [Cf. F. proportionner. Cf. {Proportionate}, v.]
1. To adjust in a suitable proportion, as one thing or one part to another; as, to proportion the size of a building to its height; to proportion our expenditures to our income. In the loss of an object we do not proportion our grief to the real value . . . but to the value our fancies set upon it. --Addison.
2. To form with symmetry or suitableness, as the parts of the body. Nature had proportioned her without any fault. --Sir P. Sidney.
3. To divide into equal or just shares; to apportion.
