The given expression is:

\[
\frac{\sqrt{8} + \sqrt{32} - \sqrt{50}}{\sqrt{2} + \sqrt{18}}
\]

Let's simplify this step by step.

### Step 1: Simplify each square root term.

1. \(\sqrt{8} = \sqrt{4 \times 2} = 2\sqrt{2}\)
2. \(\sqrt{32} = \sqrt{16 \times 2} = 4\sqrt{2}\)
3. \(\sqrt{50} = \sqrt{25 \times 2} = 5\sqrt{2}\)
4. \(\sqrt{2}\) remains as it is.
5. \(\sqrt{18} = \sqrt{9 \times 2} = 3\sqrt{2}\)

Now, substitute these simplified forms into the expression.

\[
\frac{2\sqrt{2} + 4\sqrt{2} - 5\sqrt{2}}{\sqrt{2} + 3\sqrt{2}}
\]

### Step 2: Combine like terms.

- The numerator becomes:
  \[
  (2\sqrt{2} + 4\sqrt{2} - 5\sqrt{2}) = 1\sqrt{2}
  \]
  
- The denominator becomes:
  \[
  (\sqrt{2} + 3\sqrt{2}) = 4\sqrt{2}
  \]

Thus, the expression simplifies to:

\[
\frac{\sqrt{2}}{4\sqrt{2}}
\]

### Step 3: Simplify the fraction.

Since \(\sqrt{2}\) is present in both the numerator and denominator, they cancel out:

\[
\frac{1}{4}
\]

### Final Answer:
The simplified expression is \(\frac{1}{4}\).
