Bonsoir,

M=

-1/2 +35/36

= -18/36 +35/36

= 17/36

N=

-5/3 *(-16/28 +9/28)

= -5/3* -7/28

= 35/ 84

P=

(4/14 -3/4) * (-15/18 - 4/18)=

1/14 * -19/18

= -19/ 252

Réponse :

bonjour

Explications étape par étape :

M = -1/2 +7/4 * 5/9 = -1/2 + 35/36 = -18/36+ 35/36 = 17/36

N= -5/3 * (-4/7 - +9/28) = 5/12

P = (2/7 - 3/14) * (-5/6 - 2/9) = 1/14* (-19/18) = -19 / 252
