Question

Diferenta a doua numere este 10 , iar raportul lor este 2.25 . Afla numerele.

Answer 1

$x-y=10$
$\frac{x}{y} =2.25= \frac{225}{100} = \frac{9}{4}$
$\frac{x}{y} = \frac{9}{4} ==\ \textgreater \ 4x=9y$
$x= \frac{9y}{4}$
$\frac{9y}{4}-y=10$
$9y=4y=40$
$5y=40$
$y= \frac{40}{5}=8$
$x= \frac{9y}{4}=x= \frac{9*8}{4}=9*2=18$
