Bonjour
Complète :
1 = 2/... = 3/... = 6/... = 8/... = 12/...
1 = 2/2 = 3/3 = 6/6 = 8/8 = 12/12
1 = .../10 = .../2 = .../4 = .../100
1 = 10/10 = 2/2 = 4/4 = 100/100
2 = 4/... = .../10 = .../100 = .../4
2 = 4/2 = 20/10 = 200/100 = 8/4
... = 4/2
... = 2 x 10 = 20
... = 2 x 100 = 200
... = 2 x 4 = 8
1/2 = 2/... = 4/... = .../10 = .../12
1/2 = 2/4 = 4/8 = 5/10 = 6/12
... = 2 x 2 = 4
... = 4 x 2 = 8
... = 10 / 2 = 5
... = 12 / 2 = 6
