\frac{122412}{132613}~~\text{Verificam daca se simplifica} \\ \\
122412 = 2^2 \times 3 \times 101^2 \\
132613 = 13 \times 101^2 \\
\Longrightarrow ~~\text{Fractia se simplifica cu } 101^2 \\ \\
\frac{122412}{132613} = \frac{2^2 \times 3 \times 101^2}{13 \times 101^2} = \frac{2^2 \times 3 }{13}= \frac{4 \times 3}{13}= \boxed{\frac{12}{13}} [/tex]
