WebWhen we say x is directly proportional to y, we mean that as x increases, y increases and as x decreases, y decreases. This can be alternatively written as x/y = constant. Direct proportionality is represented by x ∝ y (or) x = ky where k is a constant. x∝y can be crudely read as x is proportional to y.

WebAll inverse variation relationship are verbalized in written problems as inverse variations or as inversely proportional. Examples of inverse variation or inversely proportional equations are: x = k y x = k y x x varies inversely as y y x x varies as the inverse of y y x x varies inversely proportional to y y x x is inversely proportional to y y WebDirect and inverse proportionality is used to show how two quantities are related to each other. The symbol used to denote proportionality is “∝”. For example, if we say that a is proportional to b, this is represented by “ a ∝ b “. If we say that a is inversely proportional to b, this is denoted as “ a ∝1 / b “.
