10% = 0,1
also 349 * 0,1 = 34,9 Franken

Weitere Möglichkeiten der Berechnung:

1.)    $${\mathtt{349}}{\mathtt{\,\times\,}}{\mathtt{10}}\% = {\frac{{\mathtt{349}}}{{\mathtt{10}}}} = {\mathtt{34.9}}$$

 

2.)  10%= 10/100 = 0.1

       $${\mathtt{349}}{\mathtt{\,\times\,}}{\mathtt{0.1}} = {\frac{{\mathtt{349}}}{{\mathtt{10}}}} = {\mathtt{34.9}}$$

    

      $${\frac{{\mathtt{349}}{\mathtt{\,\times\,}}{\mathtt{10}}}{{\mathtt{100}}}} = {\frac{{\mathtt{349}}}{{\mathtt{10}}}} = {\mathtt{34.9}}$$
