Answer 1

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

(1 20/24 - 9/24) * х = 2 1/12            (5/8 - 2/8) : х = 1/6

1 11/24х = 2 1/12                             3/8 : х = 1/6

35/24х = 25/12                                 х = 3/8 : 1/6

24х * 25 = 35 *12                             х = 3/8 * 6

600х = 420                                       х = 18/8

х = 420 : 600                                    х = 2 2/8

х = 0,7                                              х = 2 1/4

4) х * (11/12 - 1/4) = 3/8

х * (11/12 - 3/12) = 3/8

8/12х = 3/8

х = 3/8 : 8/12

х = 3/8 * 12/8

х = 36/64

х = 9/16
