1. Réponse maudmarine
A= 1/2 + 3/2 × 7/3
A = 1/2 + 21/6
A = 1 x 3 / 2 x 3 + 21/6
A = 3/6 + 21/6
A = 24/6
A = 6 x 4 / 6 x 1
A = 4
B= (1/2 + 3/2 ) × 7/3
B = 4/2 x 7/3
B = 28/6
B = 2 x 14 / 2 x 3
B = 14/3
C= 20/9 - 5/3 × 2/3
C = 20/9 - 10/9
C = 10/9
D = ( 20/9 - 5/3 ) × 2/3
D = (20/9 - 5 x 3 / 3 x 3) x 2/3
D = (20/9 - 15/9) x 2/3
D = 5/9 x 2/3
D = 10/27
