Answer 1

Odpowiedź:

3 - 1 i 5/6 = 2 i 6/6 - 1 i 5/6 = 1 i 1/6

2 i 3/8 - 5/8 = 1 i 11/8 - 5/8 = 1 i 6/8 = 1 i 3/4

1 i 5/9 + 2 i 1/3 + 3 i 1/6 = 1 i 10/18 + 2 i 6/18 + 3 i 3/18 = 6 i 19/18 = 7 i 1/18

3 i 4/5 + 2 i 1/2 + 7/10 = 3 i 8/10 + 2 i 5/10 + 7/10 = 5 i 20/10 = 7

4 i 1/6 - 1 i 3/5 + 2 i 1/2 = 4 i 5/30 - 1 i 18/30 + 2 i 15/30 = 3 i 35/30 - 1 i 18/30 + 2 i 15/30 = 2 i 17/30 + 2 i 15/30 = 4 i 32/30 = 5 i 2/30 = 5 i 1/15

4 i 1/2 - 2 i 3/5 - 1 i 2/3 = 4 i 15/30 - 2 i 18/30 - 1 i 20/30 = 3 i 45/30 - 2 i 18/30 - 1 i 20/30 = 1 i 27/30 - 1 i 20/30 = 7/30
