ETYM French, from Latin proportio; pro before + portio part or share. Related to Portion.
1. Harmonious arrangement or relation of parts or elements within a whole (as in a design); SYN. balance.
2. Magnitude or extent; SYN. dimension.
3. The quotient obtained when the magnitude of a part is divided by the magnitude of the whole; SYN. proportionality.
The relation of a part to the whole (usually expressed as a fraction or percentage). In mathematics two variable quantities x and y are proportional if, for all values of x, y = kx, where k is a constant. This means that if x increases, y increases in a linear fashion.
A graph of x against y would be a straight line passing through the origin (the point x = 0, y = 0). y is inversely proportional to x if the graph of y against 1/x is a straight line through the origin. The corresponding equation is y = k/x. Many laws of science relate quantities that are proportional (for example, Boyle’s law). + prikaži više
