Wie rechnet man 144:180???

Hallo Anonymous,

die Reihenfolge ist leider etwas durcheinander gekommen.

Gruß radix !

1.) schriftlich rechnen :                          2.) Rechner benutzen:    $${\frac{{\mathtt{144}}}{{\mathtt{180}}}} = {\frac{{\mathtt{4}}}{{\mathtt{5}}}} = {\mathtt{0.8}}$$

3.Faktorisieren dann kürzen:   $${\frac{{\mathtt{3}}{\mathtt{\,\times\,}}{\mathtt{2}}{\mathtt{\,\times\,}}{\mathtt{2}}{\mathtt{\,\times\,}}{\mathtt{3}}{\mathtt{\,\times\,}}{\mathtt{2}}{\mathtt{\,\times\,}}{\mathtt{2}}}{\left({\mathtt{2}}{\mathtt{\,\times\,}}{\mathtt{3}}{\mathtt{\,\times\,}}{\mathtt{3}}{\mathtt{\,\times\,}}{\mathtt{2}}{\mathtt{\,\times\,}}{\mathtt{5}}\right)}} = {\frac{{\mathtt{4}}}{{\mathtt{5}}}} = {\mathtt{0.8}}$$
