The ratio of two terms ‘x’ and ‘y’ is denoted by x:y. In general, the ratio of a number x to a number y is defined as the quotient of the numbers x and y. The numerator of the ratio is called the antecedent (x) and the denominator is called consequent (y) of the ratio. COMPARISON OF TWO OR MORE RATIOS Two or more ratios may be compared by reducing the equivalent fractions to a common denominator and then comparing the magnitudes of their numerator. Thus, suppose 2:5, 4:3 and 4:5 are three ratios to be compared then the fractions  and  are reduced to equivalent fractions with a common denominator. For this, the denominator of each is changed to 15 equal to the L.C.M. their denominators....
