5/9:3
1 1/2: 3
2 1/4: 6
myślę że wszystko dobrze :)
4/5 : 2 = 4/5 : 2/1 = 4/5 x 1/2 = 2/5
2/7 : 3 = 2/7 : 3/1 = 2/7 x 1/3 = 6/7
4/7 : 2 = 4/7 : 2/1 = 4/7 x 1/2 = 2/7
5/9 : 3 = 5/9 : 3/1 = 5/9 x 1/3 = 5/27
1 1/2 : 3 = 3/2 : 3/1 = 3/2 x 1/3 = 1/2
2 1/4 : 6 = 9/4 : 6/1 = 9/4 x 1/6 = 9/24 = 3/8
Mam nadzieje że pomogłam ;))
