Bonjour,
Calculer chaque expression:
A= 3/8 x (4/9 + 2/3)
A= 3/8 x (4/9 + 6/9)
A= 3/8 x 10/9
A= 30/72
A= 5/12
B= 3/8 x 4/9 + 2/3
B= 12/72 + 2/3
B= 12/72 + 48/72
B= 60/72
B= 5/6
C= 7/5 x (3/10 + 1/5)
C= 7/5 x (3/10 + 2/10)
C= 7/5 x 5/10
C= 35/50
C= 7/10
D= 7/5 x 3/10 + 1/5
D=21/50 + 1/5
D= 21/50 + 10/50
D= 31/50
Bonne journée à toi! :)
