Sagot :
bonjour,
A = - 5 /6 + 1 /8
= - 20/24 + 3 /24
= - 17 /24
B = 66 / 40 = 33 /20
C = - 7 /6 * - 9 /5
= 63/30
= 21/10
d = - 14 /5 * 15 /26
= - 210 / 130
= - 21 /13
Réponse :
salut ;)
Explications étape par étape
A= -5/6 +1/8
= -40/48+ 6/48
= -34/48 = -17/24
B= -11/8 × -6/-5
= 66/-40 = 33/-20
c= -7/6 × -9/5
= 63/30 = 21/10
D= 7× -2/5× 15/26
= -14/5 × 15/26
= -14 × 3/26 = -42/26
= -21/13
bonne chance :)
