Bonsoir,
A = 7/6 + 2/3
A = 7/6 + 2 x 2/3 x 2
A = 7/6 + 4/6
A = 11/6
B = 4/5 + 2/15
B = 4 x 3/5 x 3 + 2/15
B = 12/15 + 2/15
B = 14/15
C = 7/5 + 1
C = 7/5 + 5/5
C = 7 + 5/5
C = 12/5
D = 5 + 3/2
D = 5/1 + 3/2
D = 5 x 2/1 x 2 + 3/2
D = 13/2
E = 8/9 - 1/3
E = 8/9 - 1 x 3/3 x 3
E = 8/9 - 3/9
E = 5/9
F = 3 - 5/7
F = 3 x 7/1 x 7 - 5/7
F = 21/7 - 5/7
F = 16/7
G = 13/12 - 19/48
G = 13 x 4/12 x 4 - 19/48
G = 52/48 - 19/48
G = 33/48
H = 17/13 - 11/65
H = 17 x 5/13 x 5 - 11/65
H = 85/65 - 11/65
H = 74/65
J'espère que mon aide te seras bénéfique!
