Answer 2

Odpowiedź:

3 i 2/9 + 1 i 5/6 = 3 i 4/18 + 1 i 15/18 = 4 i 19/18 = 5 i 1/18

7 i 3/4 - 5 i 1/3 = 7 i 9/12 - 5 i 4/12 = 2 i 5/12

4 i 2/15 + 2 i 7/10 = 4 i 4/30 + 2 i 21/30 = 6 i 25/30 = 6 i 5/6

11 i 1/11 + 3 i 2/33 = 11 i 3/33 + 3 i 2/33 = 14 i 5/33

4 i 5/7 - 1 i 1/2 = 4 i 10/14 - 1 i 7/14 = 3 i 3/14

2 i 3/7 - 2/5 = 2 i 15/35 - 14/35 = 2 i 1/35
