The problem asks us to find the missing percentage in the equation: $x\%$ of $36 = 18$. We need to find the value of $x$.

1. Problem Description

The problem asks us to find the missing percentage in the equation: $x\%$ of $36 = 18$. We need to find the value of $x$.

2. Solution Steps

We can rewrite the given equation as:

$\frac{x}{100} \times 36 = 18$

To solve for $x$, we first multiply both sides of the equation by 100:

$x \times 36 = 18 \times 100$

$36x = 1800$

Now, we divide both sides of the equation by 36:

$x = \frac{1800}{36}$

$x = \frac{18 \times 100}{18 \times 2}$

$x = \frac{100}{2}$

$x = 50$

3. Final Answer

50
