well, is really "x", which oddly enough is the 100%, and we also know that 12 is 96% of that, so


\begin{array}{ccll} Amount&\%\\ \cline{1-2} x & 100\\ 12& 96 \end{array} \implies \cfrac{x}{12}~~=~~\cfrac{100}{96} \\\\\\ \cfrac{x}{12} ~~=~~ \cfrac{25}{24}\implies 24x=300\implies x=\cfrac{300}{24}\implies x=\cfrac{25}{2}\implies x=12.5
