Question

AJUTOR DE LA BAIETI!?SI FETE Stiind ca x/y = 0,2 , calculati valoarea raportului: 5y-2x/5y+2x. ( /- fractie)

Answer 1

$\frac{2}{10}= \frac{1}{5} =\ \textgreater \ y=[tex] \frac{5y-2x}{5y+2x}= \frac{5x*5-2x}{5*5x+2} = \frac{25x-2x}{25x+2x} = \frac{23x}{27x} simplificata fractia cu x=\ \textgreater \ \frac{23}{27}$
