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.
We can equivalently write  y is proportional to 1/ x , which y = c/x would represent. If a linear function transforms 0, a and b into 0, c and d, and if the product a b c d is not zero, we say a and b are proportional to c and d. An equality of two ratios such as, where no term is zero, is called a proportion. The force acting on a certain object due to gravity is directly proportional to the object's mass; the constant of proportionality between the mass and the force is known as gravitational acceleration.
