Odpowiedź:
7 - 4 i 2/9 = 6 i 9/9 - 4 i 2/9 = 2 i 7/9
6 - 3 i 1/11 = 5 i 11/11 - 3 i 1/11 = 2 i 10/11
8 - 2 i 3/7 = 7 i 7/7 - 2 i 3/7 = 5 i 4/7
6 - 1 i 5/9 = 5 i 9/9 - 1 i 5/9 = 4 i 4/9
10 - 5 i 4/11 = 9 i 11/11 - 5 i 4/11 = 4 i 7/11
b)
7 - 4 2/9 = 2 7/9
c)
6 - 3 1/11 = 5 11/11 - 3 1/11 = 2 10/11
d)
8 - 2 3/7 = 5 4/7
e)
6 - 1 5/9 = 4 3/9
