bonjour pouvez vous m'aider pour ceci: 1-(3/4+1/2x(7)) merci d'avance​

bonjour

1-(3/4 + 1/2 × (7))

= 1 - ( 3/4 + 7/2)

= 1 - (3/4 + 7×2/2×2)

= 1 - (3/4 + 14/4)

= 1 - ( 17/4)

= 1/1 - 17/4

= 1×4/1×4 - 17/4

= 4/4 - 17/4

= -13/4

Bonjour,

Calculer:

1-(3/4+1/2x(7))= 1 - (3/4 +7/2)= 1- (3 +7x2)/4= 1-17/4= (1x4-17)/4= -13/4
