(8 1/6 - 5/18) : 14/27 - (10 7/8 : 3/4 * 2/3 + 5 3/7 : 6 1/3) * 3/17 =  11 3/7

8 1/6 - 5/18 = 8 3/18 - 5/18 = 7 21/18 - 5/18 = 6 16/18 = 6 8/9

6 8/9 : 14/27 =  62/9 * 27/14 = 93/7 = 13 2/7

10 7/8 : 3/4 * 2/3 = 87/8*4/3 * 2/3 = 29/3 = 9 2/3

5 3/7 : 6 1/3 = 38/7 : 19/3 = 38/7*3/19 = 6/7

9 2/3 +  6/7  = 9 14/21 + 18/21 = 9 32/21 = 10 11/21

10 11/21*3/17 = 221/21*3/17 =  13/7 = 1 6/7

13 2/7 - 1 6/7 = 12 9/7 - 1 6/7 = 11 3/7
