Odpowiedź:
a) 5- 4/7= 4 i 7/7-4/7=4 i 3/7
b) 3 i 2/5 -1 i 4/5= 2 i 7/5 - 1 i4/5= 1 i 3/5
c) 7 i 4/11 - 2 i 9/11= 6 i 15/11- 2 i 9/11= 4 i 6/11
Szczegółowe wyjaśnienie:
5 - 4/7 = 4 i 7/7 - 4/7 = 4 i 3/7
3 i 2/5 - 1 i 4/5 = 2 i 7/5 - 1 i 4/5 = 1 i 3/5
7 i 4/11 - 2 i 9/11 = 6 i 15/11 - 2 i 9/11 = 4 i 6/11
