Bonsoir,

C= ( -4 + 3 x 2/7 ) : ( 3 / 14 ) 

C=(-4+3\times\dfrac{2}{7}):\dfrac{3}{14}\\\\C=(-4+\dfrac{6}{7}):\dfrac{3}{14}\\\\C=(-\dfrac{28}{7}+\dfrac{6}{7}):\dfrac{3}{14}\\\\C=(-\dfrac{22}{7}):\dfrac{3}{14}\\\\C=(-\dfrac{22}{7})\times\dfrac{14}{3}\\\\C=(-\dfrac{22}{1})\times\dfrac{2}{3}\\\\C=-\dfrac{44}{3}

C = (-4 + 6/7) : 3/14)
(- 28/7 +6/7) : 3/14
- 22/7 x 14/3
-22 x 2/3
-44/3
