The expression in the image is:

\[
1 - \frac{1}{1 + \frac{1}{2}}
\]

Let's solve this step by step.

### Step 1: Simplify the denominator

We need to simplify the denominator first:

\[
1 + \frac{1}{2}
\]

This can be written as:

\[
1 + \frac{1}{2} = \frac{2}{2} + \frac{1}{2} = \frac{3}{2}
\]

So, now the expression becomes:

\[
1 - \frac{1}{\frac{3}{2}}
\]

### Step 2: Simplify the fraction

To simplify \(\frac{1}{\frac{3}{2}}\), we take the reciprocal of \(\frac{3}{2}\), which is \(\frac{2}{3}\). So, the expression becomes:

\[
1 - \frac{2}{3}
\]

### Step 3: Perform the subtraction

Now, subtract \(\frac{2}{3}\) from 1. First, express 1 as a fraction with the same denominator:

\[
1 = \frac{3}{3}
\]

So, we have:

\[
\frac{3}{3} - \frac{2}{3} = \frac{1}{3}
\]

### Final Answer:
\[
1 - \frac{1}{1 + \frac{1}{2}} = \frac{1}{3}
\]
