Answer 1

Odpowiedź:

2 i 1/2 + 7 i 1/5 = 2 i 5/10 + 7 i 2/10 = 9 i 7/10

6 i 7/12 + 2 i 13/15 = 6 i 35/60 + 2 i 52/60 = 8 i 87/60 = 9 i 27/60 = 9 i 9/20

10 i 3/4 - 8 i 5/12 = 10 i 9/12 - 8 i 5/12 = 2 i 4/12 = 2 i 1/3

3 i 1/6 - 1 i 5/8 = 3 i 4/24 - 1 i 15/24 = 2 i 28/24 - 1 i 15/24 = 1 i 13/24

4 i 5/12 - 2 i 17/30 = 4 i 25/60 - 2 i 34/60 = 3 i 85/60 - 2 i 34/60 = 1 i 51/60 = 1 i 17/20

6 i 3/4 + 7/8 + 5 i 1/2 = 6 i 18/24 + 21/24 + 5 i 12/24 = 11 i 51/24 = 13 i 3/24 = 13 i 1/8

8 i 2/3 + 1 i 1/12 - 5/8 = 8 i 16/24 + 1 i 2/24 - 15/24 = 9 i 18/24 - 15/24 = 9 i 3/24 = 9 i 1/8

12 i 3/4 - 1/8 - 2 i 3/5 = 12 i 30/40 - 5/40 - 2 i 24/40 = 13 i 1/40
