Answer 1

1,25 = 125/100 = 5/4 ( am simplificat cu 25 )
 0,02 = 2/100 = 1/50 ( am simplicat cu 2 )
 4,5 = 45/10 = 9/2 ( am simplificat cu 5 )
5,085 = 5085/10 = 1017/2 ( am simplificat cu 5)
0,9 = 9/10
12,3 = 123/10
0,75 = 75 / 100 = 3/4 ( am simplificat cu 25 )
2,375 = 2375/1000 = 95/4 ( am simplificat cu 25 )
8,1 = 81/10
19,04 = 1904/100 = 952/50 = 476/25 ( am simplificat de doua ori cu 2 )                 0,35 = 35/100 = 7/20 ( am simplificat cu 5 )
1,2 = 12/10 = 6/5  (am simplificat cu 2)
7,5 = 75 /10 = 15/2  ( am simplificat cu 5 )
15,95 = 1595/100 = 319/20 ( am simplificat cu 5)
