Bonsoir j’aurais besoin d’aide Calculer les expressions suivantes. L= -7/5 : (2/9 - 7/18) M= (4/5 + -3/2) : (-9/4 - 1/6) merci d’avance

Bonsoir,

L= -7/5 / (2/9 - 7/18)

= -7/5 /( 4/18 -7/18)

=  -7/5 /( -4/18

= -7/5 / (-2/9)

= -7/5 *-9/2

= 63/10

M= (4/5 + -3/2) / (-9/4 - 1/6)

= (8/10 - 15/10) / ( -27/12 - 2/12)

=( -7/10) / ( -29/12)

= 203/120

Bonsoir,

Calculer :

L = -7/5:(2/9-7/18)

L = -7/5:(-1/6)

L = 7/5:1/6

L = 7/5×6

L = 42/5

M = (4/5-3/2):(-9/4-1/6)

M = -7/10:(-9/4-1/6)

M = -7/10:(-29/12)

M = 7/10:29/12

M = 7/10×12/29

M = 7/5×6/29

M = 42/145

/ = fraction.

Bonne soirée.
