$(4x)/(5)$

$(20x^2y)/(25xy)$

$(4x^2y)/(5xy)$ -----------Cancel out by 5.

$(4xy)/(5y)$ ----------------Cancel out $x$

$(4x)/(5)$ -------------------Cancel out $y$

We get simplified form,

$(4x)/(5)$

Here, excluded values are:
$x!in0 & y !in0$

Because, the denominator becomes zero when $x or y =0$ .
And 0 in the denominator gives $oo$ . While, $oo$ is not-defined number.

How do you simplify (20x^2y)/(25xy)(20x^2y)/(25xy) and find the excluded values?
