Answer 1

a)
 5/4 = 1 i 1/4 = 1 i 25/100 = 1,25
9/2  = 4 i 1/2 = 4 i 5/10 = 4,5
13/5 = 26/10 = 2,6
23/8  = 2875/1000 = 2,875
3/25  = 12/100 = 0,12
5/16 = 5,0 : 16 = 0,3125

b)
11/40 = 11,0 : 40 = 0,275
7/20 = 35/100 = 0,35
27/50 = 54/100 = 0,54
39/200 = 195/1000 = 0,195
224/125 = 1792/1000 = 1,792
47/5000 = 94/10000 = 0,0094

c)
3/30 = 1/10 = 0,1
21/15 = 7/5 = 14/10 = 1,4
33/24 = 11/8 = 1375/1000 = 1,375
15/75 = 3/15 = 1/5 = 2/10 = 0,2
54/48 = 18/16 = 9/8 = 1 i 1/8 = 1 i 125/1000 = 1,125
69/150 = 23/50 = 46/100 = 0,46
