bonjour
2/7 + 1/6 = 12/42 + 7/42 = 19/42
19/42 de la fortune seront donnés à Elodie et Joel
Faustine aura la moitié de 19/42 = 19/42 x 1/2 = 19/84
total des 3 = 19/42 + 19/84 = 38/84 + 19/84 = 57/84
il reste les 27/84
ce reste va être partagé en 3 → 27/84 : 3 = 27/84 x 1/3 = 27 /252
Elodie = 2/7 + 27/252 = 72/252 + 27/252 = 99/252 = 11 /28
Joel = 1/6 + 27/252 = 42/252 + 27/252 = 69/252 = 23/84
Faustine = 19/84 + 27/252 = 57/252 + 27/252 = 84/252 = 1/3
