Выполним вычисления:

1) 2 2/3 - 1/3 = 2 + 2/3 - 1/3 = 2 + (2 - 1)/3 = 2 + 1/3 = 2 1/3;

2) 8 10/13 - 2 7/13 = 8 - 2 + 10/13 - 7/13 = 6 + (10 - 7)/13 = 6 + 3/13 = 6 3/13;

3) 3 14/15 - 3 = 3 - 3 + 14/15 = 0 + 14/15 = 14/15;

4) 3 - 1 11/16 = 3 - 1 - 11/16 = 2 - 11/16 = 1 + 1 - 11/16 = 1 + 16/16 - 11/16 = 1 + (16 - 11)/16 = 1 + 5/16 = 1 5/16;

5) 8 12/15 - 6 14/15 = 8 - 6 + 12/15 - 14/15 = 2 + (12 - 14)/15 = 2 - 2/14 = 1 + 1 - 2/14 = 1 + 14/14 - 2/14 = 1 + (14 - 2)/14 = 1 12/14;

6) 9 1/3 - 8 2/3 = 9 - 8 + 1/3 - 2/3 = 1 + (1 - 2)/3 = 1 - 1/3 = 3/3 - 1/3 = (3 - 1)/3 = 2/3.
