14 5/11 - 9/28*1 22/27 - 19/110*5/6 = 13 8/11,

1) 9/28 * 1 22/27 = 9/28 * 49/27 = 7/12,
2) 19/110 * 5/6 = 19/132,
3) 14 5/11 - 7/12 - 19/132 = 159/11 - 7/12 - 19/132 =
= 1908/132 - 77/132 - 19/132 = 1812/132 = 151/11 = 13 8/11,

5 1/3*9 - 2 3/4*5 1/3 - 19 1/2*1 5/9 = 3,

1) 5 1/3 * 9 = 16/3 * 9 = 16 * 3 = 48,
2) 2 3/4 * 5 1/3 = 11/4 * 16/3 = 44/3 = 14 2/3,
3) 19 1/2 * 1 5/9 = 39/2 * 14/9 = 91/3 = 30 1/3,
4) 48 - 14 2/3 - 30 1/3 = 47 3/3 - 14 2/3 - 30 1/3 = 3,

3)
2 1/4*2 2/27 + (3 1/6 + 4 5/6*11/29) * 1 1/15 = 10,

1) 2 1/4 * 2 2/27 = 9/4 * 56/27 = 14/3 = 4 2/3,
2) 4 5/6 * 11/29 = 29/6 * 11/29 = 11/6 = 1 5/6,
3) 3 1/6 + 1 5/6 = 4 6/6 = 5,
4) 5 * 1 1/15 = 5 * 16/15 = 16/3 = 5 1/3,
5) 4 2/3 + 5 1/3 = 9 3/3 = 10,

4)
(5 5/14 - 4 17/42) * 11 1/5 - 2 2/3*3/5*2 11/12 = 6,

1) 5 5/14 - 4 17/42 = 75/14 - 185/42 = 225/42 - 185/42 = 40/42 = 20/21,
2) 20/21 * 11 1/5 = 20/21 * 56/5 = 32/3 = 10 2/3,
3) 2 2/3 * 3/5 * 2 11/12 = 8/3 * 3/5 * 35/12 = 14/3 = 4 2/3,
4) 10 2/3 - 4 2/3 = 6
