$3frac{126-12}{900}</var>=<var>3 frac{114}{900}</var>=<var>3 frac{38}{300}</var>=<var>3 frac{19}{150}$;

 

$frac{12}{99}</var><var>= frac{4}{33}$;

 

 

Answer 2

0,2 (18) = 2/10 + 18/99 · 1/10 = 99·2/990 + 18/990 = (198 + 18)/990 = 216/990 = 12/55

 

3,12 (6) = 3 +12/100 + 6 /9 · 1/100 = 3 + 3/25 + 2/300 = 3 + 3/25 + 1/150 = 3 + 19/150 =

= 3 19/150 = 469/150

3,(6) = 3 +6/9  = 3 + 2/3 = 3 2/3 = 11/3

0,(12) = 12/99 = 4/33
