Problem Solving (PS) | Re: If 5x = 6y and xy 0, what is the ratio of 1/5*x to 1/6*y ?

 

­The ratio of 1/5*x to 1/6*y is \(\frac{(\frac{1}{5}*x)}{(\frac{1}{6}*y)}=\frac{x}{5}*\frac{6}{y}=\frac{6x}{5y}\), not \(\frac{6y}{5x}\).­ Since from the stem x/y = 6/5, then \(\frac{6x}{5y}=(\frac{6}{5})^2=\frac{36}{25}\).

Answer: B.

Hope it's clear.­
