Question

Scrie sub forma de fractii ordinare ,ireductibile :
30,(123); 0,6(54); 0,24(3); 3,0(6) .

Answer 1

30,(123)=(30123-30)/999=30093/999=simplificam cu  3=
10031/333

0,6(54)=(654-6)/990=
648/990=simplificam cu 2=
324/495=simplificam cu 3=
108/165 prin 3=
36/55

0,24(3)=(243-24)/900=219/900=
simplificam cu 3
73/300

3,0(6)=(306-30)/90=
276/90=simplificam cu 3
92/30=prin 2
=46/15
