1. Réponse caro67000
-45/36 + 25/36 × (-9/5) =
-45/36 + ( -9*25/5*36) =
-45/36 - 225/5*36 =
-45/36 - 45/36 = 0
1- (1/7 + 3/4 × 11/5)=
1- ( 1/7 + 33/20 ) =
1 - ( 20/140 + 231/140) =
140/140 - 251/140 =
-111/140 -
2. Réponse Fabrice
-45/36 + 25/36 * (-9/5)
= -45/36 + 5*5*(-9)/36*5
= -45/36 - 45/36
= -90/36
= -10/4
= -5/2
1 - (1/7 + 3/4 * 11/5)
= 1-(1/7 + 33/20)
= 1-(20/140+231/140)
= 140/140-251/140
= -111/140
En espérant t'avoir aidé.
