Answer 2

Odpowiedź:

7/9 - 2/9 = 5/9

1 i 5/12 - 1/12 = 1 i 4/12 = 1 i 1/3

4 i 2/3 - 3 = 1 i 2/3

6 i 6/7 - 2 i 4/7 = 4 i 2/7

1 - 2/3 = 3/3 - 2/3 = 1/3

4 - 3/8 = 3 i 8/8 - 3/8 = 3 i 5/8

6 - 5 i 4/10 = 5 i 10/10 - 5 i 4/10 = 6/10 = 3/5

8 - 2 i 6/11 = 7 i 11/11 - 2 i 6/11 = 5 i 5/11

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

6 i 5/14 - 7/14 = 5 i 19/14 - 7/14 = 5 i 12/14 = 5 i 6/7

8 i 3/9 - 2 i 5/9 = 7 i 12/9 - 2 i 5/9 = 5 i 7/9

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