Bonjour,
:
5/3 1/3 4/3
5/6 7/6 3/2
1 11/6 2/3
5/3 + 7/6 + 2/3 =
10/6 + 7/6 + 4/6 = 21/6
21/6 - 4/3 - 2/3 =
21/6 -8/6 - 4/6 = 9/6 = 3/2
21/6 - 7/6 - 3/2 =
21/6 -7/6 -9/6 =
21/6 -5/3 -5/6 =
21/6 -10/6 - 5/6 = 6/6 =1
21/6 -5/3 -4/3=
21/6 -10/6 - 8/6 = 3/6 = 1/3
21/6 - 1 - 2/3 =
21/6 - 6/6 - 4/6 = 11/6
