Помогите решить пример 

 Вычислите

 (8целых1/6-5/18):14/27-(10целых7/8:3/4*2/3+5целых3/7:6целых1/3)*3/17 =13целых5/14

Answer 1

8_1/6 - 5/18 = 49*3/18 - 5/18 = 142/18

142/18 : 14/27 = 142/18 * 27/14 = 71*3/14 = 213/14

10_7/8:3/4 = 87/8 * 4/3 = 29/2

29/2 * 2/3 = 29/3

5_3/7 : 6_1/3 = 38/7 : 19/3 = 38/7 * 3/19 = 6/7

29/3 + 6/7 = (29*7 + 6*3)/(3*7) = 221/21

221/21 * 3/17 = 13/7

213/14 - 13/7 = 213/14 - 26/14 = 187/14 = 13_5/14
