Bonjour vous pouvez m'aider:
A = [tex]\frac{2}{3}[/tex] x 5 - [tex]\frac{5}{9}[/tex]
B = ( [tex]\frac{5}{12}[/tex] + [tex]\frac{1}{3}[/tex] ) x [tex]\frac{9}{4}[/tex]
C = -3 + [tex]\frac{40}{15}[/tex] x [tex]\frac{5}{4}[/tex]µ
D = [tex]\frac{3}{7}[/tex] - ( -[tex]\frac{4}{9}[/tex] + [tex]\frac{5}{7}[/tex] )
E = ( -[tex]\frac{2,5}{7}[/tex] + [tex]\frac{2}{14}[/tex] ) : [tex]\frac{8}{7}[/tex]
F = [tex]2 + \frac{1}{3}[/tex]
[tex]\frac{[tex]2 + \frac{1}{3}[/tex]}{-3 + \frac{1}{3} }[/tex]

Explications étape par étape :

■ A = 10/3 - 5/9 = 30/9 - 5/9 = 25/9

■ B = (5/12 + 4/12) x 9/4 = 9/12 x 9/4 = 3/4 x 9/4 = 27/16

■ C = -3 + 8/3 x 5/4 = -3 + 10/3 = -9/3 + 10/3 = 1/3

■ D = 3/7 - (-28/63 + 45/63) = 3/7 - 17/63 = 27/63 - 17/63 = 10/63

■ E = (-5/14 + 2/14) x 7/8 = -3/14 x 7/8 = -3/2 x 1/8 = -3/16

■ F = 6/3 + 1/3 = 7/3

■ G = ?
