Answer 1

Ответ:

1.1,1

2.24

3.-5

4.10

5.13,9

Пошаговое объяснение:

1) 8-6,9=1,1

2) 29-5=24

3) -7/3+(-19/6+1/2)=-14/6-19/6+1/2=-33/6+3/6=-30/6=-5

4)-6,4+13,24+3,16=10

5)-1,42+28,34-13,02=28,34-14,44=13,9

Answer 2

Let's calculate each of these expressions step by step:

1. (-5,7) + (3,9) + (-1,2) + (4,1) = (-5 + 3 - 1 + 4, 7 + 9 - 2 + 1) = (1, 15)

2. (13,8) + (-1,7) + (15,2) + (-3,3) = (13 - 1 + 15 - 3, 8 - 7 + 2 - 3) = (24, 0)

3. To add mixed numbers, first, convert them to improper fractions: -2 1/3 = -7/3 -3 1/6 = -19/6

Now, add them: -7/3 + (-19/6 + 1/2) = -7/3 + (-19/6 + 3/6) = -7/3 + (-16/6) = -7/3 - 8/3 = -15/3 = -5

4. (-2,6) - (3,8) - (-13,24) - (-3,16) = (-2.6 - 3.8 + 13.24 + 3.16) = (7.24, 29.58)

5. (3,2) - (4.62) - (-28.34) - (13.02) = (3.2 - 4.62 + 28.34 - 13.02) = (15.9, 15.3)

So, the results are:

1. (1, 15)
2. (24, 0)
3. -5
4. (7.24, 29.58)
5. (15.9, 15.3)
