Bonsoir,

405/450 =81/90= 9/10 ->T

840/1050 = 84/105 = 28/35 = 4/5 -> I

360/432 =  180/216 = 90/108 = 45/54 = 5/6 -> E

420/480 = 42/48 = 21/24 = 7/8 ->R

1056/1188 =176/198 = 88/99 =8/9 -> S

=> TIERS

Q= 6/7 = 6/7 * 24/24 =144/168

U = 10/11  = 10/11 *13/13 = 130/143

A = 2/3 = 2/3 *36/36 = 72/108

R= 7/8 = 7/8* 15/15 =105/120

T = 9/10 = 9/10/12/12 =108/120
