$${\frac{\left({\mathtt{2}}{\mathtt{\,\small\textbf+\,}}{\frac{{\mathtt{1}}}{{\mathtt{2}}}}\right)}{{\mathtt{5}}}} = {\frac{{\mathtt{1}}}{{\mathtt{2}}}} = {\mathtt{0.5}}$$                           $${\mathtt{2}}{\mathtt{\,\small\textbf+\,}}{\frac{{\mathtt{1}}}{{\mathtt{2}}}} = {\frac{{\mathtt{4}}}{{\mathtt{2}}}}{\mathtt{\,\small\textbf+\,}}{\frac{{\mathtt{1}}}{{\mathtt{2}}}} = {\frac{{\mathtt{5}}}{{\mathtt{2}}}}$$     ;     $${\frac{{\mathtt{5}}}{\left({\mathtt{2}}{\mathtt{\,\times\,}}{\mathtt{5}}\right)}} = {\frac{{\mathtt{1}}}{{\mathtt{2}}}}$$

 

1/2 von 28 = 14        ;    $${\frac{\left({\mathtt{2}}{\mathtt{\,\small\textbf+\,}}{\frac{{\mathtt{1}}}{{\mathtt{2}}}}\right)}{{\mathtt{5}}}}{\mathtt{\,\times\,}}{\mathtt{28}} = {\mathtt{14}}$$

Hallo Anonymous,

 

das Ergebnis ist 14.

Rechnung:

$${\frac{{\mathtt{5}}}{{\mathtt{2}}}} = {\mathtt{2.5}}$$

$${\frac{\left({\frac{{\mathtt{5}}}{{\mathtt{2}}}}\right)}{{\mathtt{5}}}} = {\frac{{\mathtt{1}}}{{\mathtt{2}}}} = {\mathtt{0.5}}$$

0,5 von 28 ist 14.
