$\bf a)\ \ \it \dfrac{2}{3}=\dfrac{12}{18} \Rightarrow \begin{cases} \it \dfrac{18}{3}=\dfrac{12}{2}\ \ (am\ inversat\ extremii)\\ \\ \\ \it \dfrac{2}{12}=\dfrac{3}{18}\ \ (am\ inversat\ mezii)\\ \\ \\ \it \dfrac{3}{2}=\dfrac{18}{12}\ \ (am\ inversat\ rapoartele)\end{cases}$

$\bf b)\ \ \it \dfrac{6}{5}=\dfrac{12}{10} \Rightarrow \begin{cases} \it \dfrac{10}{5}=\dfrac{12}{6}\ \ (am\ inversat\ extremii)\\ \\ \\ \it \dfrac{6}{12}=\dfrac{5}{10}\ \ (am\ inversat\ mezii)\\ \\ \\ \it \dfrac{5}{6}=\dfrac{10}{12}\ \ (am\ inversat\ rapoartele)\end{cases}$
