Sagot :
Bonjour,
K= 1/-8 + 5/4+ -7/6
= - 3/24 +30/24 - 28/24
= -1/34
L= 1 + -15/7 + -3/-5
= 35/35 - 75/35 - 21/35
= -61/35
M= -2 + 5/6-23/10-3/-5
= -120/60 + 50/60 - 156/60 +36/60
= -190/60 = -19/6
N= -3/10+-9/8+7/5+3/2
= -24/80 -90/80 +112/80 + 120/80
= 118/80 = 59/40
P=-11+1/11+1/6-6
- 726/66 + 6/66 + 11/66 - 396/66
= -1105/66
R=2/3- -7/4-1/5
120/60 + 105/60 - 12/60
= 213/60
K=-19
L=-29
M=-18
N=-45
P=23
R=-6
Voilà les réponses fallait juste justifier
