2,2 + 1 i 1/4 = 2,2 + 5/4 = 2,2 + 1,25 = 3,45
6 i 2/3 - 3,125 = 6 i 2/3 - 3 i 125/1000 = 6 i 2/3 - 3 i 1/8 = 6 i 16/24 - 3 i 3/24 = 3 i 13/24
4,50 - 2 i 1/2 + 3 i 1/3 = 4 i 5/100 - 2 i 1/2 + 3 i 1/3 = 4 i 5/100 - 2 i 1/2 + 3 i 1/3 = 4 i 1/20 - 2 i 10/20 + 3 i 1/3 = 3 i 21/20 - 2 i 10/20 + 3 i 1/3 = 1 i 11/20 + 3 i 1/3 = 1 i 33/60 + 20/60 = 1 i 53/60
