Bonjour
Calculer et simplifier au maximum le résultat obtenu.
A= -9/7 x -28/3 / 6/15
A = 252/27 : 6/15
A = 252/27 x 15/6
A = 3 780/162
A = (54 x 70) / (54 x 3)
A = 70/3
B= -2/3 x 6/8 -3/4 /1/-2
B = - 12/24 - 3/4 x - 2
B = (12 x - 1) / (12 x 2) + 6/4
B = - 1/2 + (2 x 3) / (2 x 2)
B = - 1/2 + 3/2
B = 2/2
B = 1.
