The expression provided in the image is:

\[
4.6 - \left\{ 3.2 - \left( 1.8 - \frac{2.2 - 1.8}{1.8} \right) \right\}
\]

Let's simplify it step by step:

1. **Simplify inside the fraction:**
   \[
   \frac{2.2 - 1.8}{1.8} = \frac{0.4}{1.8} \approx 0.2222
   \]

2. **Substitute the fraction back into the equation:**
   \[
   1.8 - 0.2222 \approx 1.5778
   \]

3. **Simplify the expression within the second set of brackets:**
   \[
   3.2 - 1.5778 = 1.6222
   \]

4. **Now simplify the entire expression:**
   \[
   4.6 - 1.6222 = 2.9778
   \]

Thus, the simplified result is approximately:

\[
\boxed{2.98}
\]
