The expression from the image is:

\[
\frac{36 \frac{1}{2}}{27 \frac{2}{3} - \left( \frac{1}{2} \right)^{-2}}
\]

Let's break this down step by step:

### Step 1: Convert mixed fractions to improper fractions.

- \( 36 \frac{1}{2} = \frac{73}{2} \)
- \( 27 \frac{2}{3} = \frac{83}{3} \)

### Step 2: Simplify the exponent.

The expression \( \left( \frac{1}{2} \right)^{-2} \) means we take the reciprocal of \( \frac{1}{2} \) and square it:

\[
\left( \frac{1}{2} \right)^{-2} = \left( \frac{2}{1} \right)^{2} = 4
\]

### Step 3: Substitute and simplify.

Now, the expression becomes:

\[
\frac{\frac{73}{2}}{\frac{83}{3} - 4}
\]

### Step 4: Combine the terms in the denominator.

To subtract \( 4 \) from \( \frac{83}{3} \), we write \( 4 \) as \( \frac{12}{3} \):

\[
\frac{83}{3} - 4 = \frac{83}{3} - \frac{12}{3} = \frac{71}{3}
\]

### Step 5: Simplify the overall fraction.

The expression now looks like:

\[
\frac{\frac{73}{2}}{\frac{71}{3}} = \frac{73}{2} \times \frac{3}{71} = \frac{73 \times 3}{2 \times 71} = \frac{219}{142}
\]

Thus, the simplified result is:

\[
\frac{219}{142}
\]
