The compound ratio of the inverse ratios of the ratios x : yz , y : zx , z : xy is :
Compound ratio is the ratio of product of first terms in every ratio to that of product of second term in every ratio.
Thus, inverse ratios of the ratios of x : yz , y : zx , z : xyÂ
= $$\frac{yz}{x}$$ , $$\frac{zx}{y}$$ , $$\frac{xy}{z}$$
Product of ratios = $$\frac{x^2y^2z^2}{xyz}$$
= $$\frac{xyz}{1}$$
Thus, compound ratio = xyz : 1
