Question

Transformă in fracții ordinare numerele :
19,(5) =
0,5(3) =
32,(41) =
1,21(05) =
2.Tranaformatii in fractii ireductibile numerele :
6,3(5) =
2,(4) =
13,7 (14) =

​

Answer 1

1. 19,(5) = (195-19)/9 = 176/9

0,5(3) = (53-5)/90 = 52/90

32,(41) = (3241-32)/99 = 3209/99

1,21(05) = (12105-121)/990= 11984/990

2. 6,3(5) = (635-63)/90 = 572/90 simplifcam cu 2 = 286/45

2,(4) = (24-2)/9= 22/9

13,7(14) = (13714-137)/990= 13577/990
