$100$

#### Explanation:

color(blue)("9% of any number" can be expressed as color(blue)(9/100x.

Thus, if $\text{9% of some number}$ is equal to $9$, we can say that

$\frac{9}{100} x = 9$

To find the unknown value, $x$, multiply both sides by $\frac{100}{9}$.

$x = \frac{100}{9} \cdot 9$

$x = 100$

Therefore, $\text{9% of 100} = 9$.
