Пошаговое объяснение:

2 - 8/5 = 1 5/5 - 1 3/5 = 2/5

4 - 9/11 - 27/11 = 3 11/11 - 9/11 - 2 5/11 = 3 2/11 - 2 5/11 = 2 13/11 - 2 5/11 = 8/11

2 - 16/17 - 18/17 = 1 17/17 - 16/17 - 1 1/17 = 1 1/17 - 1 1/17 = 0

3 - 21/19 - 16/19 = 2 19/19 - 1 2/19 - 16/19 = 1 17/19 - 16/19 = 1 1/19

2 - (26/27 + 24/27) = 2 - 50/27 = 1 27/27 - 1 23/27 = 4/27

2 - (24/25 - 1/25) = 1 25/25 - 23/25 = 1 2/25
