Bonjour ,
pour la 1 ère question:
A=(17)/(3-10)
= 17/-7
=-17/7
B=(-2-(-17))/(5-8)
=(-2+17)/-3
=15/-3
=-5
C=(-4-5)/(5-6)
= -9/-1
=9
D=(6-6×4)/(6×2-2)
=(6-24)/(12-2)
=-18/10
E=2-(-18/-3)+6
=2-6+6
=2
F=((-21)+7×3)/((-13)+17×(-4))
=0/((-13)+17×(-4))
=0
G=(-2×(-4)×3×(-3))/(-4,5×2)
=(8×(-9))/(-9)
=8
H=(-5×(-3)×(-4))/(-1)×(-1)×(-1)
=-60/-1
= 60
I=(-9×(-3)-(-3)×(-5))/(15÷(-3)-2)
= (27-15)/(-5-2)
= 12/-7
=-12/7
j'ai fait la première question il te suffit de vérifier ces réponses à l'aide de la calculatrice et de classer ces résultats dans l'ordre croissant.
bonne journée !
