Bonsoir

A = 28 : 6 = 28/6 = 14/3 ≈ 4,7
B = 500 : 300 = 500/300 = 5/3 ≈ 1,7
C = 4 : 6 = 4/6 = 2/3 ≈ 0,7
D = 6 : 8 = 6/8 = 3/4 = 0,75
E = 65 : 65 = 65/65 = 1
F = 6 : 3 = 6/3 = 2
G = 9 : 6 = 9/6 = 3/2 = 1,5
H = 99 : 36 = 99/36 = 11/4 = 2,75
I = 42 : 9 = 42/9 = 14/3 ≈ 4,7
J = 15 : 9 = 15/9 = 5/3 ≈ 1,7
K = 8 : 12 = 8/12 = 2/3 ≈ 0,7
L= 33 : 44 = 33/44 = 3/4 = 0,75
M = 7 : 7 = 7/7 = 1
N = 18 : 9 = 18/9 = 2
O = 45 : 30 = 45/30 = 3/2 = 1,5
P =140 : 30 = 140/30 = 14/3 ≈ 4,7
Q = 25 :15 = 25/15 = 5/3 ≈ 1,7
R = 20 : 30 = 2/3 ≈ 0,7
S = 63 : 84 = 3/4 = 0,75
T = 11 :11 = 11/11 = 1
U = 400 : 200 = 400/200 = 2
V = 24 : 16 = 24/16 = 3/2 = 1,5
W = 98 : 21 = 98/21 = 14/3 ≈ 4,7
X = 36 : 54 = 36/54 = 2/3 ≈ 0,7
Y = 21 : 28 = 21/28 = 3/4 = 0,75
Z = 512 : 512 = 512/512 = 1
Je vous remercie beaucoup ce que j'avais commencé correspond au votre Merci
Avec plaisir :)
