a) 0,5= 1/2 0,75 = 3/4
1/2 + 2/3 = 3/6 + 4/6 = 7/6
7/6 - 3/4 = 14/12 - 9/12 = 5/12
b) 0,2³ = 0,008 = 8/1000
24/125 = 192/1000
8/1000 + 192/1000 = 200/1000 = 1/5
c) 2 i 2/5 = 12/5 półtorej = 3/2
12/5 razy 3/2 = 36/10 = 18/5
1,125 = 1 i 1/8 = 9/8
2 razy 9/8 = 18/16
9/8 : 18/16 = 9/8 razy 16/18 = 2/2 = 1
