5) 21 5/17

6) 2 15/16

Пошаговое объяснение:

===================================================

1) 2 + (1 - 12/17) = 2 + (17/17 - 12/17) = 2 + 5/17 = 2 5/17

2) 19 - (2 + 19/11) = 19 - (22/11 + 19/11) = 19 - 41/11 = 19 - 3 8/11 = 18 11/11 - 3 8/11 =

= 15 3/11

3) 81 + (2 - 13/44) = 81 + (1 44/44 - 13/44) = 81 + 1 31/44 = 82 31/44

4) 53 - (4 - 3/14) = 53 - (3 14/14 - 3/14) = 53 - 3 11/14 = 52 14/14 - 3 11/14 = 49 3/14

5) 26 - (5 - 5/17) = 26 - (4 17/17 - 5/17) = 26 - 4 12/17 = 25 17/17 - 4 12/17 = 21 5/17

6) 12 - (10 - 15/16) = 12 - (9 16/16 - 15/16) = 12 - 9 1/16 = 11 16/16 - 9 1/16 = 2 15/16
