Szczegółowe wyjaśnienie:
Odpowiedź:
3/4 + 5/8 = 6/8 + 5/8 = 11/8 = 1 i 3/8
5/6 - 2/3 = 5/6 - 4/6 = 1/6
zad.3
3/5 + 1/10 = 6/10 + 1/10 = 7/10
2/3 + 1/6 = 4/6 + 1/6 = 5/6
1 i 5/6 + 4 i 1/12 = 1 i 10/12 + 4 i 1/12 = 5 i 11/12
4/5 - 3/10 = 8/10 - 3/10 = 5/10 = 1/2
8/3 - 8/9 = 24/9 - 8/9 = 16/9 = 1 i 7/9
2 i 1/2 - 1/4 = 2 i 2/4 - 1/4 = 2 i 1/4
zad.4
1/2 + 1/3 = 3/6 + 2/6 = 5/6
3/4 - 2/3 = 9/12 - 8/12 = 1/12
