Объяснение:

1) 3 1/9 : 2 1/3 - 2 5/6 = 28/9 * 3/7 - 17/6 = 4/3 - 17/6 = 8/6 - 17/6 = -9/6 = -1  1/2

2) 1 5/7 - 4 3/13 : 1 19/26 = 12/7 - 55/13 * 26/45 = 12/7 - 22/9 = -39/56

3) 10 16/17 : 8 5/11 + 1 2/3 = 186/17 * 11/93 + 5/3 = 22/17 + 5/3 = 151/51 = 2  49/51

4) 47/48 : 3 13/27 - 13/16 = 47/48 * 94/27 - 13/16 = 3  265/648
