Calculer chaque expression en detaillant les calculs . - D :  ( -  4 ) x 0.278 x ( - 2 ) x 5 x ( - 2.5 ) - E :  (-10) x 8.5 x 0 x (1 .5) x (-2.5) - F :  (-5) x

D :  ( -  4 ) x 0.278 x ( - 2 ) x 5 x ( - 2.5 )
=[(-4)x(-2.5)]x(5x(-2))x0.278
=10x(-10)x0.278
=-100x0.278
=27.8

E :  (-10) x 8.5 x 0 x (1 .5) x (-2.5)
=0

F :  (-5) x (-8) x (-125) x (-2) x (-1) x (-0.5)
=[-8x(-125)]x[-5x(-2)]x[-1x(-0.5)]
=1000x10x0.5
=10000x0.5
=5000

G :  26 / (-3 - 2 x 5)
=26/(-3-10)
=-26/13
=-2
