1/4 + 1/2 = 1/4 + 2/4 = 3/4
1/3 + 7/12 = 4/12 + 7/12 = 1
8/15 + 3/5 = 8/15 + 9/15 = 17/15 = 1 i 2/15
3/4 - 5/8 = 6/8 - 5/8 = 1/8
1/4 - 3/20 = 5/20 - 3/20 = 2/20
7/10 - 3/20 = 14/20 - 3/20 = 7/20
1/3 + 1/2 = 2/6 + 3/6 = 5/6
3/4 - 2/5 = 15/20 - 8/20 = 7/20
5/8 + 1/7 = 35/56 + 8/56 = 43/56
7/9 + 4/5 = 35/45 + 36/45 = 71/45 = 1 i 26/45
4/5 + 5/8 = 32/40 + 25/40 = 57/40 = 1 i 17/40
5/7-1/6 = 30/42 - 7/42 = 23/42
3/10 + 8/15 = 9/30 + 14/30 = 23/30
5/6 - 4/9 = 30/36 - 16/36 = 14/36 = 7/18
3/8 + 5/12 = 9/24 + 10/24 = 19/24
i to nie wiem co za działania są:
3 /3/4 + 2 1/7
6 3 /4+ 4 1/3
5 4/15 - 1 2/5
9 1/5 -3 7/9
7 10/21 + 2 9/14
tylko tyle ale nadal coś
