Aider moi svp je suis en 4eme et je galere sur ce calcule A -7/6:3/4 B 3/8:-3/4 C -5/9:-8/3 voila réponder moi vite svp

Bonjour,

A -7/6:3/4

A = - 7/6 x 4/3

A = - 28/18

A = (2 x - 14) (2 x 9)

A = - 14/9

B 3/8:-3/4

B = 3/8 x - 4/3

B = - 12/24

B = (2 x - 1) / (2 x 12)

B = - 1/2

C -5/9:-8/3

C = - 5/9 x - 3/8

C = 15/72

C = (3 x 5) / (3 x 24)

C = 5/24.
