Step 2.1

Factor $z$ out of $z^{3}$ .

$\frac{z}{z + 4} \cdot \frac{1}{z \cdot z^{2}}$

Step 2.2

Cancel the common factor.

$\frac{z}{z + 4} \cdot \frac{1}{z \cdot z^{2}}$

Step 2.3

Rewrite the expression.

$\frac{1}{z + 4} \cdot \frac{1}{z^{2}}$

Step 3

Multiply $\frac{1}{z + 4}$ by $\frac{1}{z^{2}}$ .

$\frac{1}{(z + 4) z^{2}}$

Step 4

Reorder factors in $\frac{1}{(z + 4) z^{2}}$ .

$\frac{1}{z^{2} (z + 4)}$
