-2,8• (-35):(-0,49)-(-13,25):(-5,3):(-0,8)

Let's break down the expression step by step.

The expression is:

\[ -2.8 \cdot \left(-\frac{35}{-0.49}\right) - \left(-\frac{13.25}{-5.3}\right) : (-0.8) \]

First, compute each component separately:

1. Evaluate \(-\frac{35}{-0.49}\): \[ -\frac{35}{-0.49} = \frac{35}{0.49} \approx 71.4286 \]

2. Now calculate \(-2.8 \cdot 71.4286\): \[ -2.8 \cdot 71.4286 \approx -200 \]

3. Next, evaluate \(-\frac{13.25}{-5.3}\): \[ -\frac{13.25}{-5.3} = \frac{13.25}{5.3} \approx 2.5 \]

4. Combine the results: \(-200 - 2.5\)

5. Finally, resolve the division by \(-0.8\): Since we resolved \( - \left(-\frac{13.25}{-5.3}\right) = 2.5\), you divide 2.5 by -0.8: \[ \frac{2.5}{-0.8} = -3.125 \]

Thus, our expression simplifies to: \[ -200 + 3.125 \approx -196.875 \]

Therefore, the final answer is:

\[ \boxed{-196.875} \]
