Bonjour,
A = 2/3 - 4/3 x 5/2
A = 2/3 - 20/6
A = 2/3 - (2 x 10) / (2 x 3)
A = 2/3 - 10/3
A = - 8/3
B = 5 + (1 + 1/8) : 3/4
B = 5 + [(1 x 8) / (1 x 8) + 1/8] : 3/4
B = 5 + (8/8 + 1/8) : 3/4
B = 5 + 9/8 : 3/4
B = 5 + 9/8 x 4/3
B = 5 + 36/24
B = (5 x 2) / (1 x 2) + (12 x 3) / (12 x 2)
B = 10/2 + 3/2
B = 13/2
C = 6/5 : (1/15 - 3/4)
C = 6/5 : [(1 x 4) / (15 x 4) - (3 x 15) / (4 x 15)]
C = 6/5 : (4/60 - 45/60)
C = 6/5 : - 41/60
C = 6/5 x - 60/41
C = - 360/205
C = (5 x - 72) / (5 x 41)
C = - 72/41.
