Odpowiedź:
1 i 2/7 = 9/7
1 i 1/3 = 4/3
2 i 1/5 = 11/5
2 i 3/4 = 11/4
4 i 1/2 = 9/2
3 i 7/8 = 31/8
6 i 5/6 = 41/6
8 i 3/13 = 107/13
zad 5
4 i 3/7 + 3 i 4/7 = 7 i 7/7 = 8
3 i 5/8 + 7 i 7/8 = 10 i 12/8 = 11 i 4/8 = 11 i 1/2
4 - 4/7 = 3 i 7/7 - 4/7 = 3 i 3/7
8 - 2 i 1/4 = 7 i 4/4 - 2 i 1/4 = 5 i 3/4
2 i 3/4 - 2/2 = 2 i 3/4 - 2/4 = 2 i 1/4
6 i 1/4 + 2 i 1/2 = 6 i 1/4 + 2 i 2/4 = 8 i 3/4
