Bonsoir,

Calculer :

E = -4/9 x 8

E = - 32/9

F = 8/9 x -2 x 3

F = - 16/9 x 3

F = - 48/9

F = (3 x - 16) / (3 x 3)

F = - 16/3

G = -15/16 x 12/35

G = - 180/560

G = (20 x - 9) / (20 x 28)

G = - 9/28

H = -4/21 x 9/-12 x 28/27

H = 36/252 x 28/27

H = 1 008/6 804

H = (252 x 4) / (252 x 27)

H = 4/27.
