Usando o método da equação pra determinar

x=0,414444...*(100)\\100x=41,444....\\100x=41+ \frac{4}{9} \\
\\100x= \frac{373}{9} \\
\\900x=373\\
\\\boxed{x= \frac{373}{900} }

y=0,8235235...~*(10)\\10y=8,235235...\\
\\10y=8+ \frac{235}{999} \\
\\10y= \frac{8227}{999}\\
\\\boxed{y= \frac{8227}{9990}  }

z=0,1235235...*(10)\\10z=1,235235...\\
\\10z=1+ \frac{235}{999} \\
\\10z= \frac{1234}{999} \\
\\\boxed{z= \frac{1234}{9990} }
