Answer 1

Ответ:

1) 5 1/2 + (-8 5/6) = 5 1/2 - 8 5/6

5 1/2 = 5.5

8 5/6 = 8.8333

5.5 - 8.8333 ≈ -3.3333

2) 4 1/3 + (-7 5/9) = 4 1/3 - 7 5/9

4 1/3 = 4.3333

7 5/9 = 7.5556

4.3333 - 7.5556 ≈ -3.2223

3) 3 3/8 + (-9 1/2) = 3 3/8 - 9 1/2

3 3/8 = 3.375

9 1/2 = 9.5

3.375 - 9.5 = -6.125

4) 2 1/3 + (-4 5/6) = 2 1/3 - 4 5/6

2 1/3 = 2.3333

4 5/6 = 4.8333

2.3333 - 4.8333 ≈ -2.5000

5) 1 1/12 + (-5 1/6) = 1 1/12 - 5 1/6

1 1/12 = 1.0833

5 1/6 = 5.1667

1.0833 - 5.1667 ≈ -4.0834

6) 3 2/15 + (-9 1/3) = 3 2/15 - 9 1/3

3 2/15 = 3.1333

9 1/3 = 9.3333

3.1333 - 9.3333 ≈ -6.2000
