mam nadzieje, ze pomogłam ;)
Hej!
4/12 = (4 : 4)/(12 : 4) = 1/3
4/8 = (4 : 4)/(8 : 4) = 1/2
3/15 = (3 : 3)/(15 : 3) = 1/5
6/9 = (6 : 3)/(9 : 3) = 2/3
8/10 = (8 : 2)/(10 : 2) = 4/5
6/21 = (6 : 3)/(21 : 3) = 2/7
4/16 = (4 : 4)/(16 : 4) = 1/4
10/50 = (10 : 10)/(50 : 10) = 1/5
8/30 = (8 : 2)/(30 : 2) = 4/15
15/25 = (15 : 5)/(25 : 5) = 3/5
28/36 = (28 : 4)/(36 : 4) = 7/9
10/70 = (10 : 10)/(70 : 10) = 1/7
