1)х- 24 5/8 = 30 5/6 + 41 7/12

х- 24 5/8 = 30 10/12 + 41 7/12

х- 24 5/8 = 71 17/12

х- 24 5/8 = 72 5/12

x= 72 5/12 + 24 5/8

x = 72 10/24 + 24 15/24

x= 96 25/24

x= 97 1/24

3)x - 92 3/10 = 8 19/20 + 4 2/15

x - 92 3/10 = 8 57/60 + 4 8/60

х - 92 3/10 = 12 65/60

x - 92 3/10 = 13 5/60

x - 92 3/10 = 13 1/12

x = 13 1/12 + 92 3/10

x=13 5/60 + 92 18/60

x= 105 23/60
