B)
29/9-11/6= 58/18-33/18=25/18=1i 7/18
37/7-11/4= 148/28 - 77/28= 71/28= 2i21/28= 2 i3/4
7/3-12/7= 49/21-36/21= 13/21
Odpowiedź:
4 - 2 i 2/5 = 3 i 5/5 - 2 i 2/5 = 1 i 3/5
2 - 1 i 5/8 = 1 i 8/8 - 1 i 5/8 = 3/8
5 - 3 i 1/7 = 4 i 7/7 - 3 i 1/7 = 1 i 6/7
3 i 2/9 - 1 i 5/6 = 3 i 4/18 - 1 i 15/18 = 2 i 22/18 - 1 i 15/18 = 1 i 7/18
5 i 2/7 - 2 i 3/4 = 5 i 8/28 - 2 i 21/28 = 4 i 36/28 - 2 i 21/28 = 2 i 15/28
2 i 1/3 - 1 i 5/7 = 2 i 7/21 - 1 i 15/21 = 1 i 28/21 - 1 i 15/21 = 13/21
