Ответ:
- 7 14/15 + 2 1/15 = 9 + 15/15 = 10.
- 9 21/27 + 12 13/27 = 21 + 34/27 = 22 7/27.
- 1 − 12/19 = 19/19 − 12/19 = 7/19.
- 8 − 3 6/15 = 4 9/15 = 4 3/5.
- 12 − 11 6/11 = 5/11.
- 16 3/13 − 6 8/13 = 15 16/13 − 6 8/13 = 9 8/13.
- 13 4/9 − 2 8/9 = 12 13/9 − 2 8/9 = 10 5/9.
- 10 7/16 − 4 12/16 = 9 23/16 − 4 12/16 = 5 11/16.
- 29 49/53 − 8 40/53 = 21 9/53.
