We are asked to simplify the given expression: $\frac{x}{x^2-4x}$.

1. Problem Description

We are asked to simplify the given expression: $\frac{x}{x^2-4x}$.

2. Solution Steps

First, we factor the denominator:

$x^2 - 4x = x(x-4)$.

Now we can rewrite the expression as:

$\frac{x}{x(x-4)}$.

Next, we can cancel the common factor $x$ in the numerator and the denominator, provided that $x \neq 0$.

$\frac{x}{x(x-4)} = \frac{1}{x-4}$.

3. Final Answer

The simplified expression is $\frac{1}{x-4}$.
