3 Fünftel sind von 120 kilometern was ?

Hallo Anonymous,

deine Frage war wohl so gemeint:

$${\frac{{\mathtt{3}}}{{\mathtt{5}}}}$$    von  x  =  120 km   =>    3/5 *x = 120   =>   x = 120*5/3 = 200   [km]

Antwort:  3/5 von 200 km = 120 km   ;   $${\frac{{\mathtt{3}}}{{\mathtt{5}}}}{\mathtt{\,\times\,}}{\mathtt{200}}{km} = {\mathtt{120}}{km}$$  

Gruß radix !

$${\frac{{\mathtt{3}}}{{\mathtt{5}}}}{\mathtt{\,\times\,}}{\mathtt{120}}{km} = {\mathtt{72}}{km}$$

120 * 3/5  = 72  

$${\frac{{\mathtt{1}}}{{\mathtt{5}}}}{\mathtt{\,\times\,}}{\mathtt{120}}{km} = {\mathtt{24}}{km}$$        =>     $${\mathtt{3}}{\mathtt{\,\times\,}}{\mathtt{24}}{km} = {\mathtt{72}}{km}$$  

   $${\frac{{\mathtt{3}}{\mathtt{\,\times\,}}{\mathtt{120}}}{{\mathtt{5}}}} = {\frac{{\mathtt{3}}{\mathtt{\,\times\,}}{\mathtt{2}}{\mathtt{\,\times\,}}{\mathtt{120}}}{{\mathtt{10}}}} = {\frac{{\mathtt{720}}}{{\mathtt{10}}}} = {\mathtt{72}}$$
