Рушите уравнение (3 целых - 4/7)*х = 5 целых 2/3, (1 целая 5/6 - 3/8)*х = 2 целых 1/12, (5/8 - 1/4): х = 1/6

(3 - 4/7) * х = 5 2/3                         (1 5/6 - 3/8) * х = 2 1/12

х = 5 2/3 : (3 - 4/7)                          х = 2 1/12 : (1 5/6 - 3/8)

х = 5 2/3 : 2 3/7                               х = 2 1/12 : (1 20/24 - 9/24)

х = 17/3 : 17/7                                 х = 2 1/12 : 1 11/24

х = 17/3 * 7/17                                 х = 25/12 : 35/24

х = 7/3                                              х = 25/12 * 24/35

х = 2 1/3                                           х = 50/35 = 1 15/35

                                                         х = 1 3/7


(5/8 - 1/4) : х = 1/6

х = (5/8 - 1/4) : 1/6

х = (5/8 - 2/8) : 1/6

х = 3/8 : 1/6

х = 3/8 * 6/1

х = 18/8 = 2 2/8

х = 2 1/4
