Bonsoir,
E = 4/3 - 5/2 : 9/4 x 3/7
E = 4/3 - 5/2 x 4/9 x 3/4
E = 4/3 - 20/18 x 3/4
E = 4/3 - 60/72
E = (4 x 2) / (3 x 2) - (12 x 5) / (12 x 6)
E = 8/6 - 5/6
E = 3/6
E = (3 x 1) / (3 x 2)
E = 1/2
F = 14/45 x 27/49
F = 378/2 205
F = (63 x 6) / (63 x 35)
F = 6/35
G = (13 + 1) / (13 - 1)
G = 14/12
G = (2 x 7) / (2 x 6)
G = 7/6
H = 1 - (7 + 5) / (2 x 5)
H = 1 - 12/10
H = (1 x 5) / (1 x 5) - (2 x 6) / (2 x 5)
H = 5/5 - 6/5
H = - 1/5.
