Answer 1

(8 1/6 - 5 1/8 ) / 14/27 - (10 7/8 / 3/4  * 2/3 + 5 3/7  / 6 1/3 ) * 3/17
8 1/6 - 5 /18  = 7 7/6 - 5/18 = 7 21/18 - 5/18 = 7 16/18 = 7 8/9
7 8/9  /14/27  = 71/9  / 14/27  = 213/14
10 7/8  /3/4 = 87/8 / 3/4= 29/2
29/2 * 2/3 = 29/3
5 3/7  /  6 1/3  = 38/7  / 19/3 = 6/7
29/3 + 6/7 = 221/21
213/14 - 221/21 = 639/42 - 442/42  = 197/42
197/42 *3/17 =197/238
