Пошаговое объяснение:

1) 4 13/17 + 5 4/17 = 4 + 5 + 13/17 + 4/17 = 9 + (13 + 4)/17 = 9 + 17/17 = 9 + 1 = 10;

2) 3 8/11 + 2 6/11 = 3 + 2 + 8/11 + 6/11 = 5 + (8 + 6)/11 = 5 + 14/11 = 5 + 1 3/11 = 6 3/11;

3) 1 - 16/21 = 21/21 - 16/21 = (21 - 16)/21 = 5/21;

4) 5 - 2 3/8 = 5 - 2 - 3/8 = 3 - 3/8 = = 2 + 1 - 3/8 = 2 + 8/8 - 3/8 = 2 + 5/8 = 2 5/8;

5) 8 4/9 - 3 7/9 = 8 - 3 + 4/9 - 7/9 = 5 - 3/9 = 5 - 1/3 = 4 + 3/3 - 1/3 = 4 2/3;

6) 12 19/44 - 6 37/44 = 12 - 6 + 19/44 - 37/44 = 6 - 18/44 = 6 - 9/22 = 5 + 22/22 - 9/22 = 5 + 13/22 = 5 13/22.
