1. Réponse aminerbt
A = 3/8 x (4/9 + 2/3)
A = 3/8 x (4/9 + 6/9)
A = 3/8 x (10/9)
A = 1/8 x (10/3)
A = 1/4 x (5/3)
A = 5/12
B=3/8x4/9+2/3
B=(3/8x4/9)+2/3
B=(1/2x1/3)+2/3
B=(1/6)+2/3
B=(1/6)+4/6
B=5/6
C=7/5x(3/10+1/5)
C=7/5x(5/10)
C=14/10x(5/10)
C=19/10
D=7/5x3/10+1/5
D=21/50+1/5
D=21/50+10/50
D=31/50
