Question

Scrie sub forma de fractie ireducri ila urmatoarele rationale:
1,26=
0,(23)=
-0,25=
2,1(3)=

Answer 1

$1,26=\frac{126}{100}~ simplificam ~cu~ 2= \frac{63}{100}$
$0,(23)=\frac{23}{99}~nu~se~simplifica~$
$-0,25=\frac{-25}{100}~Simplificam ~cu~25=\frac{-1}{4}$
$2,1(3)=\frac{213-21}{99}=\frac{192}{99}~simplificam~cu~3=\frac{64}{33}$
