А) 1 7 /15 + 2 3/15 = 3 10 /15

3 10/15 - 1 8/15 = 2 2/15

2 2/15 - 1 4/15 = 1 17/15 - 1 4/15 = 14/15


Б) 3 12/13 - 1 5/13 = 2 7/13

2 7/13 - 1 9/13 = 1 20/13 - 1 9/13 = 11/13

11/13 + 2 3/13 = 2 14/13 = 3 1/13

В) 3 2/17 + 1 12/17 = 4 14/17

4 14/17 + 2 3/17 = 7

7 - 3 8/17 = 3 9/17

Г) 5 3/14 - 1 5/14 = 3 9/14

3 9/14 + 2 9/14 = 6 4/14

6 4/14 - 4 13/14 = 1 5/14
