Bonsoir
Effectuer les calculs :
A = -16/7 x (-1/4)
A = 16/4 x 1/7
A = (4 x 4)/4 x 1/7
A = 4 x 1/7
A = 4/7
B = 5/-6 x 2/3
B = -2/6 x 5/3
B = -2/(3 x 2) x 5/3
B = -1/3 x 5/3
B = -5/9
C = 9/2 x 7/-18
C = -9/18 x 7/2
C = -9/(2 x 9) x 7/2
C = -1/2 x 7/2
C = -7/4
D = 5/4 x (-2/-15)
D = 5/4 x 2/15
D = 5/15 x 2/4
D = 5/(3 x 5) x 2/(2 x 2)
D = 1/3 x 1/2
D = 1/6
E = (-2/3) x 3/10
E = -3/3 x 2/10
E = -1 x 2/(2 x 5)
E = -1 x 1/5
E = -1/5
F = 8/5 x (-7/24)
F = -8/24 x 7/5
F = -8/(3 x 8) x 7/5
F = -1/3 x 7/5
F = -7/15
