bonjour pourriez vous m'aider svp calculer a. 1/5:(-3) b.3/8:(-6) c.-15/8:5 d.-3/6/5 e.-3/6/5 f.-7/5/6+1/5 merci davance ​

bonsoir,

a. 1/5/(-3)=

1/ (5*-3) =-1/15

b.3/8/(-6)=

3/(8/-6*8) = 3/ (-8/48)=

(3*48)/ -8 =144/ -8=

-18

c.-15/8/5

(-15*5) /8=

-45/8

d.-3/6/5

-3/(6/5) =

(-3*5)/6 =

-15/6 = -5/2

e.-3/6/5

-3/(6/5) =

(-3*5) /6 =

-15/6 =

-5/2

f.-7/5/6+1/5

-7/(5/6) +1/5

(-7 *6)/5 +1/5=

-42/5 =1/5 =

-41/5
