Answer 2

Odpowiedź:

3 i 7/9 + 6/9 = 3 i 13/9 = 4 i 4/9

2/5 + 1/3 = 6/15 + 5/15 = 11/15

3/4 - 2/3 = 9/12 - 8/12 = 1/12

7 i 1/4 - 5 i 3/4 = 6 i 5/4 - 5 i 3/4 = 1 i 2/4 = 1 i 1/2

4 i 1/6 + 2 i 7/9 = 4 i 3/18 + 2 i 14/18 = 6 i 17/18

5 i 1/4 - 4 i 7/10 = 5 i 5/20 - 4 i 14/20 = 4 i 25/20 - 4 i 14/20 = 11/20
