Explications étape par étape
Bonjour
Entre 0 et 1 nous avons 10 traits
A = 2/10 = 2/(2 x 5) = 1/5 = 0 + 1/5 = 0,2
B = 8/10 = (4 x 2)/(5 x 2) = 4/5 = 0 + 4/5 = 0,8
C = 10/10 = 1
D = 14/10 = 10/10 + 4/10 = 1 + (2 x 2)/(5 x 2) = 1 + 2/5 = 1,4
E = 20/10 = 2
F = 23/10 = 20/10 + 3/10 = 2 + 3/10 = 2,3
G = 31/10 = 30/10 + 1/10 = 3 + 1/10 = 3,1
Encadrer :
0 < A < 1
0 < B < 1
1 < D < 2
2 < F < 3
3 < G < 4
