1. Réponse maudmarine
A = 5 - ( 5 - 1 )
18 36 36
A = 5/18 - (4/36)
A = 5 x 2 / 18 x 2 - 4/36
A = 10/36 - 4/36
A = 6/36
A = 6 x 1 / 6 x 6
A = 1/6
B = 17 - ( 11 - 1 )
12 12 3
B = 17/12 - (11/12 - 1 x 4 / 3 x 4)
B = 17/12 - (11/12 - 4/12)
B = 17/12 - 7/12
B = 10/12
B = 2 x 5 / 2 x 6
B = 5/6
C = 11 - 2 + 1
6 3 6
C = 11/6 - 2 x 2 / 3 x 2 + 1/6
C = 11/6 -4/6 + 1/6
C = 7/6 + 1/6
C = 8/6
C = 2 x 4 / 2 x 3
C = 4/3
D = 23 - 3 - 1
8 4 2
D = 23/8 - 3 x 2 / 4 x 2 - 1 x 4 / 2 x 4
D = 23/8 - 6/8 - 4/8
D = 17/8 - 4/8
D = 13/8 -

Salut :)
A = 5 - ( 5 - 1 )
18 36 36
A = 10 - 4
36 36
A = 6 = 6 x 1
36 6 x 6
A = 1

B = 17 - ( 11 - 1 )
12 12 3
B = 17 - (11 - 4)
12 12 12
B = 17 - 7
12 12
B = 10 = 2 x 5
12 2 x 6
B = 5
