Bonjour !

Explications étape par étape :

A = 5 / 8 × - 3 / 2
A = - 15 / 16

B = 7 / 8 × - 3 / 8

B = - 21 / 64

C = - 3 × 4 / 5

C = - 60 / 25 = - 12 / 5

D = - 2 / 11 × - 10 / 3

D = 20 / 33

Bonjour,

5/8 × (-3/2) = (5×(-3))/(8×2) = -15/16

7/8 × (-3/8) = (7×(-3))/(8×8) = -21/64

-3 × 4/5 = (-3×4)/5 = -12/5

-2/11 × (-10/3) = (-2×(-10))/(11×3) = 20/33
