Пошаговое объяснение:1)...=3

2)=2 19_10 3)=2 4) 6 1_17

1) 3/5 + 2 4/5 = 2 7/5 = 3 2/5

2) 8 - 6 9/10 = 7 10/10 - 6 9/10 = 1 1/10

3) 1 4/9 - 5/9 = 13/9 - 5/9 = 8/9

4) 8 2/7 - 3 4/7 = 7 9/7 - 3 4/7 = 4 5/7

5) 3 12/17 + 2 6/17 = 5 18/17 = 6 1/17

6) 7 5/9 - 6 7/9 = 6 14/9 - 6 7/9                        

7) 9/13 + 7/13 = 16/13 = 1 3/13

8) 8 8/13 + 6 5/13 = 14 13/13 = 15

9) 1 3/5 - 4/5 = 8/5 - 4/5 = 4/5

10) 7/11 + 8/11 = 15/11 = 1 4/11

11) 6 4/9 - 4 = 2 4/9

12) 5 9/17 + 7 12/17 = 12 21/17 = 13 4/17

13) 1 8/13 - 9/13 = 21/13 - 9/13 = 12/13

14)10/16 + 9/16 = 19/16 = 1 3/16

15) 8 3/11 - 7 5/11 = 7 14/11 - 7 5/11 = 9/11
