Odpowiedź:

9/15 + 4/15 = 13/15

7/11 + 2/11 = 9/11

4 i 3/8 + 2 i 4/8 = 6 i 7/8

3/9 + 7/9 = 10/9 = 1 i 1/9

3 i 2/3 + 2/3 = 3 i 4/3 = 4 i 1/3

4 i 3/5 + 2/5 = 4 i 5/5 = 5

4 i 6/7 + 2 i 1/7 = 6 i 7/7 = 7

3 i 5/10 + 4 i 9/10 = 7 i 14/10 = 8 i 4/10 = 8 i 2/5

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