Х + 8 5/6 = 10 1/3
х = 10 1/3 - 8 5/6 = 10 2/6 - 8 5/6 = 1 3/6
х = 1 1/2
-------------------------------------------------------------------------
1 1/2 + 8 5/6 = 10 1/3
1 3/6 + 8 5/6 = 10 1/3
(1+8) + (3+5)/6 = 10 1/3
9 + 1 2/6 = 10 1/3
10 2/6 = 10 1/3
10 1/3 = 10 1/3
11 7/9 + у = 13 1/18
у = 13 1/18 - 11 7/9 = 13 1/18 - 11 14/18 = 1 5/18
у = 1 5/18
--------------------------------------------------------------------------------------
11 7/9 + 1 5/18 = 13 1/18
11 14/18 + 1 5/18 = 13 1/18
12 + 1 1/18 = 13 1/18
13 1/18 = 13 1/18
