Guten Morgen Anonymous,
so könnte eine Bruchrechenaufgabe dann auf dem Rechner aussehen:
Gruß radix
!
$${\frac{\left({\frac{{\mathtt{63}}}{{\mathtt{5}}}}\right)}{\left({\frac{{\mathtt{7}}}{{\mathtt{3}}}}\right)}} = \left({\frac{{\mathtt{63}}}{{\mathtt{5}}}}\right){\mathtt{\,\times\,}}\left({\frac{{\mathtt{3}}}{{\mathtt{7}}}}\right) = {\frac{{\mathtt{9}}{\mathtt{\,\times\,}}{\mathtt{3}}}{{\mathtt{5}}}} = {\frac{{\mathtt{27}}}{{\mathtt{5}}}} = {\mathtt{5}}{\mathtt{\,\small\textbf+\,}}{\frac{{\mathtt{2}}}{{\mathtt{5}}}}$$
