Odpowiedź:
2/3 + 1/2 = 4/6 + 3/6 = 7/6 = 1 i 1/6
1 i 1/6 + 6/6 = 1/6
1/6 + 1 i 3/5 = 5/30 + 1 i 18/30 = 1 i 23/30
1 i 23/30 + 6 i 7/12 = 1 i 46/60 + 6 i 35/60 = 7 i 81/60 = 8 i 21/60
2/3 + 12 i 11/24 = 16/24 + 12 i 11/24 = 12 i 27/24 = 12 i 3/24
12 i 3/24 - 7/8 = 12 i 3/24 - 21/24 = 11 i 27/24 - 21/24 = 11 i 6/24
11 i 6/24 - 1 i 3/4 = 11 i 6/24 - 1 i 18/24 = 10 i 30/24 - 1 i 18/24 = 9 i 12/24
9 i 12/24 - 3/8 = 9 i 12/24 - 9/24 = 9 i 3/24
