8 i 3/8 = 7 i 11/8
10 i 7/10 = 9 i 17/10
4 i 4/17 = 3 i 21/17
4 i 1/3 - 13/3
3 i 4/5 = 19/5
7 = 49/7
11 = nie widac całego
zad 7
6 i 7/9 - 1/3 = 6 i 7/9 - 3/9 = 6 i 4/9
5 i 1/4 - 5/8 = 5 i 2/8 - 5/8 = 4 i 10/8 - 5/8 = 4 i 5/8
1 i 1/2 - 5/9 = 1 i 9/18 - 10/18 = 27/18 - 10/18 = 17/18
7 i 3/4 - 5 i 7/9 = 7 i 27/36 - 5 i 28/36 = 6 i 63/36 - 5 i 28/36 = 1 i 35/36
