Answer 1

2/5 = 4/10 = 0,4
12 1/2 = 12 5/10 = 12,5
2 1/10 = 2,1
8 1/5 = 8 2/10 = 8,2
10 1/10 = 10,1
9 3/5 = 9 6/10 = 9,6
3/4 = 75/100 = 0,75
7/20 = 35/100 = 0,35
125 1/125 = 125 8/1000 = 125,008
23 1/8 = 23 125/1000 = 23,125
12/25 = 48/100 = 0,48
8 1/125 = 8 8/1000 = 8,008
6 1/4 = 6 25/100 = 6,25
3/25 = 12/100 = 0,12
1 1/20 = 1 5/100 = 1,05
8 3/50 = 8 6/100 = 8,06
3/8 = 375/1000 = 0,375
2 53/125 = 2 424/1000 = 2,424
7 9/25 = 7 36/100 = 7,36
2 1/25 = 2 4/100 = 2,04
7 5/8 = 7 625/1000 = 7,625
