I) 50 21/33 - (4 1/6 + 25 9/11) = 20 43/66

1) 4 1/6 + 25 9/11 = 29 11+54/66 = 29 65/66
2) 50 21/33 - 29 65/66 = 49 54/33 - 29 65/66 = 20 108-65/66 = 20 43/66

III) 43 17/25 - (9 18/25 - 4 111/125) = 38 106/125

1) 9 18/25 - 4 111/125 = 8 43/25 - 4 111/125 = 4 215-111/125 = 4 104/125
2) 43 17/25 - 4 104/125 = 42 42/25 - 4 104/125 = 38 210-104/125 = 38 106/125
