Let's solve the expression step by step:

The given expression is:

\[
3.4 \times \frac{10}{4} + 7.1 \times \frac{10}{5}
\]

### Step 1: Simplify each part.
- \(\frac{10}{4} = 2.5\), so \(3.4 \times 2.5 = 8.5\).
- \(\frac{10}{5} = 2\), so \(7.1 \times 2 = 14.2\).

### Step 2: Add the two results.
\[
8.5 + 14.2 = 22.7
\]

### Final Answer:
\[
22.7
\]
