Odpowiedź:

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

2 - 1/2 = 1 i 2/2 - 1/2 = 1 i 1/2

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

1 - 3/5 = 5/5 - 3/5 = 2/5

4 - 3/5 = 3 i 5/5 - 3/5 = 3 i 2/5

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

1 - 1/9 = 9/9 - 1/9 = 8/9

7 - 1/9 = 6 i 9/9 - 1/9 = 6 i 8/9

10 - 1/9 = 9 i 9/9 - 1/9 = 9 i 8/9
