proportional - one of the quantities in a mathematical proportion. quantity - the concept that something has a magnitude and can be represented in mathematical expressions by a constant or a variable. proportion - the quotient obtained when the magnitude of a part is divided by the magnitude of the whole.
Given two variables x and y, y is '(directly) proportional to x (x and y vary directly, or x and y are in direct variation) if there is a non-zero constant k such that. The relation is often denoted. and the constant ratio. is called the proportionality constant or constant of proportionality. If an object travels at a constant speed, then the distance traveled is proportional to the time spent traveling, with the speed being the constant of proportionality.
