Answer 1

1)-0,1
2)-3,3
3)0
4)-6
5)(-7,04) - это если там запятые,а не деление.

Answer 2

Let's solve each expression step by step:

1. (-1,6) + (-2,1) + (+3,6): When adding complex numbers, we add the real parts and the imaginary parts separately. Real parts: -1,6 + (-2,1) + 3,6 = -1,6 - 2,1 + 3,6 = -3,1 + 3,6 = 0,5 Imaginary parts: 0 Therefore, the result is 0,5.

2. (6,4) + (-10) + (+0,3): Real parts: 6,4 - 10 + 0,3 = -3,3 Imaginary parts: 0 Therefore, the result is -3,3.

3. 14 + (-25) + (-4) + (+15): Adding the numbers together, we get: 14 - 25 - 4 + 15 = 0.

4. (-3,9) + (+1,2) + (-6,1) + (+2,8): Real parts: -3,9 + 1,2 - 6,1 + 2,8 = -6,0 Imaginary parts: 0 Therefore, the result is -6,0.

5. -7/12 + (1/8) + (-5/12) + (3/4): To add fractions, we need to find a common denominator. The common denominator is 24. -7/12 = -14/24 1/8 = 3/24 -5/12 = -10/24 3/4 = 18/24

Now we can add the fractions: -14/24 + 3/24 - 10/24 + 18/24 = -3/24 = -1/8

Therefore, the result is -1/8.

To summarize:

1. (-1,6) + (-2,1) + (+3,6) = 0,5
2. (6,4) + (-10) + (+0,3) = -3,3
3. 14 + (-25) + (-4) + (+15) = 0
4. (-3,9) + (+1,2) + (-6,1) + (+2,8) = -6,0
5. -7/12 + (1/8) + (-5/12) + (3/4) = -1/8
