Answer 1

1 $\frac{2}{5}$ ( 4 $\frac{1}{7}$ - 3 $\frac{1}{14}$) = $\frac{7}{5}$ ( $\frac{29}{7}$ - $\frac{43}{14}$) = $\frac{7}{5}$ * $\frac{15}{14}$ = $\frac{3}{2}$

De la a doua parte la a 3a am amplificat 29/7 cu 2 si le-am scazut, iar de la a 3a la final am inmultit pe diagonale, asa 7/14 a devenit 1/2 iar 15/5 a devenit 3.
