How to solve inversely proportional problems
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. WebThe constant k is called the constant of variation. The word ‘inverse’ in inverse variation refers to the multiplicative inverse. The multiplicative inverse of x is 1 x. We solve inverse variation problems in the same way we solved direct variation problems. Only the general form of the equation has changed.
