Question

transforma fractiile zecimale periodice simple in fractii ordinare:

a)0,(11);1,(23);2,(45);11,(243)

b)5,(6);0,(30);12,(036);11,(423)

Answer 1

Răspuns:

a)0, (11) =11/99 ;

1, (23)=123-1/99=122/99 ;

2, (45) = 145-2/99 =143/99;

11, (243)=11243-11/999=11232/999

b)5, (6)=56-5/9=51/9

0,(30)=30/99

12, (036)=12036-12/999=12024/999

11 , (423)= 11423-11/999=11412/999
