Answer 1

11 1/12-x=9 8/9     х=11 1/12  - 9 8/9 = 11 3/36 - 9 32/36 = 1 7/36

77 4/15-x=59 8/9  х= 77 4/15 - 59 8/9 = 77 24/90 - 59 80/90 = 17 34/90 = 17 17/45

X+29 7/8= 51 5/12   х=51 5/12 - 29 7/8 = 51 10/24 - 29 21/24 = 21 13/24

60 3/14-x=41 4/21  х=60 3/14 - 41 4/21 = 60 9/42 -41 8/42= 19 1/42
