Bonjour j’aurais besoins d’aide svp 1) 3:2+-3x1:6 2) (3:2-1:6):-3 3) 3:2x-3:1:6

Bonjour,

1) 3/2+-3x1/6

= 3/2 - 3/6

= (3 x 3) / (2 x 3) - 3/6

= 9/6 - 3/6

= 6/6

= 1

2) (3/2-1/6) :-3

= [(3 x 3) / (2 x 3) - 1/6) : - 3

= (9/6 - 1/6) : - 3

= 8/6 x - 1/3

= - 8/18

= (2 x - 4) / (2 x 9)

= - 4/9

3) 3/2x-3/1:6

= - 9/2 x 1/6

= - 9/12

= (3 x - 3) / (3 x 4)

= - 3/4.

Bonjour,

1) 3:2+-3x1:6

= 3/2 - 3/6

= 3/2 - 1/2

= 2/2

= 1

2) (3:2-1:6):-3

= (3/2 - 1/6) / -3

= (9/6 - 1/6) / -3

= 8/6 x -1/3

= -8/18

= -4/9

3) 3:2x-3:1:6

= 3/2 x -3/(1/6)

= 3/2 x -3 x 6

= -27

Ou

= 3/2 x (-3/1) /6

= 3/2 x -3/6

= 3/2 x -1/2

= -3/4
