Bonjour,

Calculer :

K = -3/8/15

K = -3/8÷15

K = -3/8×1/15

K = -3×1/8×15

K = -3/8×15

K = -1/8×5

K = -1/40

L = Idem que le K

M = 12/-11/18/55

M = -12/11÷18/55

M = -12/11×55/18

M = -12×55/11×18

M = -12×5/18

M = -2×5/3

M = -10/3

N = 2/3/-6/20

M = -2/3÷6/20

M = -2/3×20/6

M = -2×20/3×6

M = -20/3×3

M = -20/9

Bonne soirée.
