Simplify the compound fractional expression.<br><br> (x-(x/y) / (y-(y/x)

castortr0y [4]

Answer:

The simplified form of the compound fractional expression is $\frac{x^2(y-1)}{y^2(x-1)}$ .

Step-by-step explanation:

Simplify the fraction as shown:

$\dfrac{x-\frac{x}{y} }{y-\frac{y}{x} }$

Take the LCM.

$\dfrac{\frac{xy-x}{y} }{\frac{xy-y}{x} }$

Simplify,

$\frac{xy-x}{y} \times\frac{x}{xy-y}$

$\frac{x^2(y-1)}{y^2(x-1)}$

Hence, the simplified form of the compound fractional expression is $\frac{x^2(y-1)}{y^2(x-1)}$ .
