Explications étape par étape
Bonjour
Quel âge a Tati :
= [(6/11 + 3)/4 - 2 x 6/11] / [(6/11 + 2)/544 - 10/816 x 6/11]
= [(6/11 + 33/11)/4 - 12/11] / [(6/11 + 22/11)/544 - 5/408 x 6/11]
= [(39/11)/4 - 12/11] / [(28/11)/544 - 6/408 x 5/11]
= (39/44 - 48/44) / (28/5984 - 1/68 x 5/11)
= (-9/44) / (7/1496 - 5/748)
= (-9/44) / (7/1496 - 10/1496)
= (-9/44) / (-3/1496)
= 9/44 x 1496/3
= 9/3 x 1496/44
= 3 x 374/11
= 1122/11
= 102 ans
