große Kartoffeln:  6 von 31   =>   $${\frac{{\mathtt{6}}}{{\mathtt{31}}}}{\mathtt{\,\times\,}}{\mathtt{100}} = {\frac{{\mathtt{600}}}{{\mathtt{31}}}} = {\mathtt{19.354\: \!838\: \!709\: \!677\: \!419\: \!4}}$$    %

normale    "            :  20 von 31  =>  $${\frac{{\mathtt{20}}}{{\mathtt{31}}}}{\mathtt{\,\times\,}}{\mathtt{100}} = {\frac{{\mathtt{2\,000}}}{{\mathtt{31}}}} = {\mathtt{64.516\: \!129\: \!032\: \!258\: \!064\: \!5}}$$  %

kleine    "             :    5  von 31    =>     $${\frac{{\mathtt{5}}}{{\mathtt{31}}}}{\mathtt{\,\times\,}}{\mathtt{100}} = {\frac{{\mathtt{500}}}{{\mathtt{31}}}} = {\mathtt{16.129\: \!032\: \!258\: \!064\: \!516\: \!1}}$$  %
