Odpowiedź:

3 i 3/5 + 6/10 = 3 i 6/10 + 6/10 = 3 i 12/10 = 4 i 2/10 = 4 i 1/5

1/7 + 5 i 6/21 = 3/21 + 5 i 6/21 = 5 i 9/21 = 5 i 3/7

1 i 5/6 + 3/4 = 1 i 10/12 + 9/12 = 1 i 19/12 = 2 i 7/12

3 i 4/5 + 2 i 5/6 = 3 i 24/30 + 2 i 25/30 = 5 i 49/30 = 6 i 19/30

2 i 5/6 + 3 i 1/4 = 2 i 10/12 + 3 i 3/12 = 5 i 13/12 = 6 i 1/12

3 i 5/6 + 2 i 3/8 = 3 i 20/24 + 2 i 9/24 = 5 i 29/24 = 6 i 5/24
