If we have proportion in the form of $\frac{a}{b}$= $\frac{c}{d}$ which is equivalent to a:b =c:d Given, proportion $\frac{1}{2}$ = $\frac{3}{6}$ a) Means of a proportion is b and c. So for the given proportion means are 2 and 3 b.) Extremes of the proportion are a and d. So extremes of a given proportion are 1 and 6 c)the product of means is bc So product of means of a given proportion are 2.3 = 6 d.) the product of extremes is ad So product of extremes of a given proportion is 1.6 = 6
