Szczegółowe wyjaśnienie:
Odpowiedź:
12/4 + 13/8 = 24/8 + 13/8 = 37/8 = 4 i 5/8
5/2 + 5/8 = 20/8 + 5/8 = 25/8 = 3 i 1/8
4/3 + 8/9 = 12/9 + 8/9 = 20/9 = 2 i 2/9
10/2 + 5/10 = 50/10 + 5/10 = 55/10 = 5 i 5/10 = 5 i 1/2
2/5 + 3/15 = 6/15 + 3/15 = 9/15 = 3/5
9/3 - 3/9 = 27/9 - 3/9 = 24/9 = 2 i 6/9
18/2 - 9/2 = 9/2 = 4 i 1/2
2/8 - 1/8 = 1/8
10/5 - 1/4 = 40/20 - 5/20 = 35/20 = 1 i 15/20 = 1 i 3/4
