37 € von welchem Grundwert ?
Unvollständige Angabe !!
Beispiel: 37 € von 580 € = 6,38 %
$${\frac{{\mathtt{37}}{\mathtt{\,\times\,}}{\mathtt{100}}}{{\mathtt{580}}}} = {\frac{{\mathtt{185}}}{{\mathtt{29}}}} = {\mathtt{6.379\: \!310\: \!344\: \!827\: \!586\: \!2}}$$
Probe: $${\frac{{\mathtt{580}}{\mathtt{\,\times\,}}{\mathtt{6.379\: \!31}}}{{\mathtt{100}}}} = {\mathtt{36.999\: \!998}}$$
