2) x + 29 7/8 = 51 5/12
x = 51 5/12 - 29 7/8
x = 51 10/24 - 29 21/24
x = 50 34/24 - 29 21/24
x = 21 13/24
Ответ: {21 13/24}
4) 60 3/14 - x = 41 4/21
x = 60 3/14 - 41 4/21
x = 60 9/42 - 41 8/42
x = 19 1/42
Ответ: {19 1/42}
6) 61 5/8 - x = 52 1/6
x = 61 5/8 - 52 1/6
x = 61 15/24 - 52 4/24
x = 9 11/24
Ответ: {9 11/24}
