[tex](\frac{1}{a} +\frac{1}{\overline{aa}}+\frac{1}{\overline{aaa}} } ):(\frac{1}{b} +\frac{1}{\overline{bb}} +\frac{1}{\overline{bbb}} )[/tex]
[tex]\frac{1}{a}(1+\frac{1}{11} +\frac{1}{111} ):\frac{1}{b}( 1+\frac{1}{11} +\frac{1}{111} )[/tex]
Se observa se reduce paranteza si ne ramane:
[tex]\frac{1}{a} :\frac{1}{b}=\frac{1}{a} \times \frac{b}{1} =\frac{b}{a}[/tex]
Deci raspunsul nostru este: [tex]\frac{b}{a}[/tex]
Atasez poza cu exercitiul, presupun ca la acesta te referi
