Answer 2

Let's break down this expression step by step:

1. (-6,49 + (-0,5) * (-7,1)): (3,51 / (-117)) - 1
2. (-6,49 + (-0,5) * (-7,1)): (-3,51/117) - 1
3. (-6,49 + 3,55): (-0,03) - 1
4. (-2,94) / (-0,03) - 1
5. 98 - 1
6. 97

So, the result of the first part of the expression is 97.

Now, let's continue with the second part:

1. (-12,5 * (-0,8) - 147) * (30 / 6,25 - 12,8) - 1074
2. (10 + 147) * (30 / 6,25 - 12,8) - 1074
3. 157 * (30 / (-6,55)) - 1074
4. 157 * (-4,58) - 1074
5. -719.06 - 1074
6. -1793.06

So, the result of the second part of the expression is -1793.06.

Now, let's move on to the third part:

1. (21 - 11,25 * 0,8) * (-32 + (-0,8) * (-6,25)) + 624
2. (21 - 9) * (-32 + (-0,8) * (-6,25)) + 624
3. 12 * (-32 + (-0,8) * (-6,25)) + 624
4. 12 * (-32 + (-5)) + 624
5. 12 * (-37) + 624
6. -444 + 624
7. 180

So, the result of the third part of the expression is 180.

Now, let's put it all together:

97 - 1793.06 + 180 = -1616.06

So, the final result of the entire expression is approximately -1616.06.
