Regula de 3 simple :
10 kg mere ........ 6 l suc
x kg mere .......... 27 l suc
x = [tex] \frac{10*27}{6} [/tex] = [tex] \frac{270}{6} [/tex] = [tex]45[/tex] l suc
10 kg mere ........ 6 l suc
x kg mere .......... 27 l suc
x = [tex] \frac{10*27}{6} [/tex] = [tex] \frac{270}{6} [/tex] = [tex]45[/tex] l suc
10 kg..................6 l Regula de 3 simpla, marimi direct proportionale
x kg...................27 l
10/x = 6/27
In proportia formata aplicam proprietatea fundamentala a proportiilor
x=10×27/6
x=270/6
x=45 l suc
x kg...................27 l
10/x = 6/27
In proportia formata aplicam proprietatea fundamentala a proportiilor
x=10×27/6
x=270/6
x=45 l suc
