2) 8
3) 3 1/2
 4) 5 3/5
5) 8 5/6
6) 10 1/14

Answer 2

Первый столбик:                                 
= 4 1/3
= 7 4/4 = 8
= 3 + (1/6 + 1/3) = 3 + (1 +2) / 6 = 3 3/6 = 3 1/2
Второй столбик:                   
= 4 8/5 = 5 3/5
= 8 + (4/9 + 7/18) = 8 + (8+7) / 18 = 8 15/18 = 8 5/6
= 9 + (3/7 + 9/14) = 9 + (6 +9) /14 = 9 15/14 = 10 1/14
