Bonjour,A=4/6+5/4-13/12
A = (4 x 2) / (6 x 2) + (5 x 3) / (4 x 3) - 13/12
A = 8/12 + 15/12 - 13/12
A = 23/12 - 13/12
A = 10/12
A = (2 x 5) / (2 x 6)
A = 5/6
B=5/11-2/3-1/2
B = (5 x 6) / (11 x 6) - (2 x 22) / (3 x 22) - (1 x 33) / (2 x 33)
B = 30/66 - 44/66 - 33/66
B = 30/66 - 77/66
B = - 47/66
C= -5/14+3/7-2/21
C = (- 5 x 3) / (14 x 3) + (3 x 6) / (7 x 6) - (2 x 2) / (21 x 2)
C = - 15/42 + 18/42 - 4/42
C = - 19/42 + 18/42
C = - 1/42
D=3/-14×-7/5
D = 21/70
D = (7 x 3) / (7 x 10)
D = 3/10
E=-3/12×2/5
E = - 6/60
E = (6 x - 1) / (6 x 10)
E = - 1/10
F=-5/2÷3/4
F = - 5/2 x 4/3
F = - 20/6
F = (2 x - 10) / (2 x 3)
F = - 10/3
G= -8/5÷-2/3
G = - 8/5 x - 3/2
G = 24/10
G = (2 x 12) / (2 x 5)
G = 12/5
H=1/9-15/9×1/6
H = 1/9 - 15/54
H = (1 x 6) / (9 x 6) - 15/54
H = 6/54 - 15/54
H = - 9/54
H = (9 x - 1) / (9 x 6)
H = - 1/6
I=1/2-(1/4+3/4×7/5)
I = 1/2 - (1/4 + 21/20)
I = (1 x 10) / (2 x 10) - [(1 x 5) / (4 x 5) + 21/20]
I = 10/20 - (5/20 + 21/20)
I = 10/20 - 26/20
I = - 16/20
I = (4 x - 4) / (4 x 5)
I = - 4/5
J=1/3+5/6÷3/2
J = 1/3 + 5/6 x 2/3
J = 1/3 + 10/18
J = (1 x 6) / (3 x 6) + 10/18
J = 6/18 + 10/18
J = 16/18
J = (2 x 8) / (2 x 9)
J = 8/9
