2) 5 1/3+2=7 1/3

3) 3 2/9+5 5/9=8 7/9

4) 8 8/11-5/11=8 3/11

Answer 2

Пошаговое объяснение:

1)

2 5/12 + 5 5/12 = (2 + 5) + (5/12 + 5/12) = 7 + 10/12 = 7 + 5/6 = 7 5/6,

2)

5 1/3 + 2 = (5 + 2) + 1/3 = 7 + 1/3 = 7 1/3,

3)

3 2/9 + 5 5/9 = (3 + 5) + (2/9 + 5/9) = 8 + 7/9 = 8 7/9,

4)

8 8/11 - 5/11 = 8 + (8/11 - 5/11) = 8 + 3/11 = 8 3/11
