Question

determinați toate fractiile de forma xy pe abc echivalente cu fractia 3 pe 8

Answer 1

$\frac{xy}{abc} = \frac{3}{8}$

$=\ \textgreater \ xy=3;x=1,y=3,sau,x=3,y=1$
$sau,x=(-1),y=(-3),sau,x=(-3),y=(-1)$

$Si,abc=8=\ \textgreater \ a=1,b=1,c=8;sau,a=1,b=2,c=4,etc$

Answer 2

$\it \dfrac{\overline{xy}}{\overline{abc}} \in\left\{\dfrac{39}{104},\ \dfrac{42}{112}, \dfrac{45}{120},\ ...\ ,\ \dfrac{99}{264}\right\}$
