13% von 320

Hallo Anonymous,

1.)     $${\mathtt{13}}\%{\mathtt{\,\times\,}}{\mathtt{320}} = {\frac{{\mathtt{208}}}{{\mathtt{5}}}} = {\mathtt{41.6}}$$      =  41,60 €

2.)  13 % = 13 / 100 = 0,13

       320 € * 0,13 = 41,60 €  

3.)   100 %   =>   320 €

           1 %   =>  320 € / 100

         13 %   =>   (320 € / 100) * 13  = 41,60 €
