To solve the given equation:

\[
\frac{(0,2-a) \cdot 28 + 44a - 40}{0,02 - a + a}
\]

Let's break it down step by step:

1. **Simplify the Denominator:**

\[
0,02 - a + a = 0,02
\]

The \( a \) terms cancel each other out.

2. **Simplify the Numerator:**

\[
(0,2-a) \cdot 28 + 44a - 40
\]

Distribute \( 28 \):

\[
(0,2 \cdot 28) - (a \cdot 28) + 44a - 40
\]

\[
5,6 - 28a + 44a - 40
\]

Combine like terms:

\[
16a + 5,6 - 40 = 16a - 34,4
\]

3. **Combine the simplified pieces:**

The entire expression becomes:

\[
\frac{16a - 34,4}{0,02}
\]

4. **Divide the Numerator by the Denominator:**

\[
(16a - 34,4) \div 0,02
\]

This would require dividing each term in the numerator by \(0,02\):

\[
\frac{16a}{0,02} - \frac{34,4}{0,02}
\]

\[
800a - 1720
\]

So the expression simplifies to:

\[
800a - 1720
\]
