(-20,47:(-8,9)+24,6•(-0,5)):0,1

Interpretation:

• Division is “:”, multiplication is “•”, decimal comma as decimal point.

Compute step by step:

1. -20,47 : (-8,9) = (-20.47) / (-8.9) = 2.3
2. 24,6 • (-0,5) = 24.6 × (-0.5) = -12.3
3. Inside parentheses: 2.3 + (-12.3) = -10.0
4. Result: (-10.0) : 0,1 = (-10.0) / 0.1 = -100

Final answer: -100
