[tex]10/100 * 70 = 1/10 * 70 = 1/1*7 = 7 %[/tex] ( am simplificat prin 10 la 10 supra 100 si tot cu 10 la 10 si 70 )
[tex] \frac{x}{100} [/tex]·70=10
[tex] \frac{x}{100} = \frac{10}{70} [/tex]
x = [tex] \frac{100*10}{70} [/tex]
x = [tex] \frac{100}{7} [/tex]
x = 14,285714 la suta
[tex] \frac{x}{100} = \frac{10}{70} [/tex]
x = [tex] \frac{100*10}{70} [/tex]
x = [tex] \frac{100}{7} [/tex]
x = 14,285714 la suta
