WebDirect 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. Now, when we say x is inversely proportional to y, we mean that as x increases, y decreases and as x decreases, y increases. This can be rewritten as xy = constant. This is represented by x ∝ 1/y. WebThen from the definition of the fourth proportional, we must have: 4: 9 :: 12 : x or in terms of the fractions we can write; 4x = 9 × 12. In other words, we have x = {9 × 12}/4 = 27.
