$${\frac{{\mathtt{191}}}{{\mathtt{255}}}} = {\mathtt{0.749\: \!019\: \!607\: \!843\: \!137\: \!3}}$$

255 is the times in minutes

$${\mathtt{103\,680}}{\mathtt{\,\times\,}}{\mathtt{7}} = {\mathtt{725\,760}}$$

What was that anonymous?

$$\left(\left({\mathtt{3}}{\mathtt{\,-\,}}{\mathtt{2}}{\mathtt{\,\times\,}}{\mathtt{x}}\right){\mathtt{\,\times\,}}\left({\mathtt{x}}{\mathtt{\,\small\textbf+\,}}{\mathtt{1}}\right)\right) = {\mathtt{3}}{\mathtt{\,\times\,}}\left({\mathtt{2}}{\mathtt{\,\times\,}}{\mathtt{x}}{\mathtt{\,-\,}}{\mathtt{3}}\right) \Rightarrow \left\{ \begin{array}{l}{\mathtt{x}} = {\frac{{\mathtt{3}}}{{\mathtt{2}}}}\\
{\mathtt{x}} = -{\mathtt{4}}\\
\end{array} \right\} \Rightarrow \left\{ \begin{array}{l}{\mathtt{x}} = {\mathtt{1.5}}\\
{\mathtt{x}} = -{\mathtt{4}}\\
\end{array} \right\}$$

$${{\mathtt{8}}}^{\left({\frac{{\mathtt{1}}}{{\mathtt{2}}}}\right)} = {\mathtt{2.828\: \!427\: \!124\: \!746\: \!190\: \!1}}$$

$${\mathtt{1}}{\mathtt{\,-\,}}{\mathtt{9}} = -{\mathtt{8}}$$

$${\frac{{\mathtt{75}}}{{\mathtt{19}}}} = {\mathtt{3.947\: \!368\: \!421\: \!052\: \!631\: \!6}}$$

1-19?  Or (-1)+19?

$$\left({\frac{{\mathtt{1}}}{{\mathtt{3}}}}\right){\mathtt{\,\times\,}}{\mathtt{27}}{\mathtt{\,-\,}}{\mathtt{10}}{\mathtt{\,-\,}}\left({\mathtt{15}}\right) = -{\mathtt{16}}$$

You find the value of x

$${{\mathtt{1.08}}}^{{\mathtt{x}}} = {\mathtt{3.076\: \!923}} \Rightarrow {{\mathtt{27}}}^{{\mathtt{x}}} = {\frac{{\mathtt{3\,076\,923}}{\mathtt{\,\times\,}}{{\mathtt{25}}}^{\left({\mathtt{x}}{\mathtt{\,-\,}}{\mathtt{3}}\right)}}{{\mathtt{64}}}} \Rightarrow {{\mathtt{27}}}^{{\mathtt{x}}} = {\frac{{\mathtt{3\,076\,923}}{\mathtt{\,\times\,}}{{\mathtt{25}}}^{\left({\mathtt{x}}{\mathtt{\,-\,}}{\mathtt{3}}\right)}}{{\mathtt{64}}}}$$
