5/6 multiplizieren ,Produkt 18

Hi, oder verstehst du es so besser ? Antwort von Anonymous ist natürlich richtig !

$${\frac{{\mathtt{5}}}{{\mathtt{6}}}}{\mathtt{\,\times\,}}{\mathtt{x}} = {\mathtt{18}}$$       ->        $${\mathtt{x}} = {\frac{{\mathtt{18}}{\mathtt{\,\times\,}}{\mathtt{6}}}{{\mathtt{5}}}}$$    =   $${\frac{{\mathtt{18}}{\mathtt{\,\times\,}}{\mathtt{6}}}{{\mathtt{5}}}} = {\frac{{\mathtt{108}}}{{\mathtt{5}}}} = {\mathtt{21.6}}$$

Gruß radix !

5/6 = 0.833333Periodisch

18/0.833333Periodisch = 21.6000000864....
