Bonsoir,
Exercice 6 en pièce jointe
Exercice 7 :
A = (11 × (-3)) / ((-5) × (-2))
A = -33/10
B = ((-3) × 2 × (-5)) / (-10 × 4)
B = 30/(-40) = -3/4
C = - ((7 × (-2) × 8) / (14 × 5))
C = - (-112/70) = 112/70 = (14 × 8) / (14 × 5)
C = 8/5
D = ((-1) × (-3) × (-2) × (-1)) / (5 × (-4))
D = (3 × 2) / (-20) = 6/(-20) = -3/10
Exercice 8 :
k) - ((-53)/(16)) = 53/16 = 3,31
l) - ((-1,7)/(-0,7)) = -1,7/0,7 = - 2,43
résultats arrondis au centième près
Bonne soirée !
