Question

ajutor dau coroana x=?​

Answer 1

Răspuns:

1$\frac{1}{3}$x+$\frac{1}{2}$=2$\frac{1}{3}$

$\frac{4}{3}$x+$\frac{1}{2}$=$\frac{7}{3}$

$\frac{8}{6}$x+$\frac{3}{6}$=$\frac{14}{6}$|-$\frac{3}{6}$

$\frac{8}{6}$x=$\frac{11}{6}$

x=11:8

x=1,375

SAU

x=$\frac{11}{6}$-$\frac{8}{6}$

x=$\frac{3}{6}$

x=0,5

Depinde daca e adunare sau inmultire, eu stiu ca era adunare daca era inainte de fractie(prima varianta), dar nu mai sunt sigur(sa comenteze cine e sigur)
