Bonjour,

a) Il faut chercher le PGCD de 1449 et 385 et diviser ensuite numérateur et dénominateur par ce PGCD.
b)Il faut chercher le PGCD de 530 et 371 et diviser ensuite numérateur et dénominateur par ce PGCD.

Bien sûr la calculatrice de collège donne le résultat final mais ne dit pas comment le trouver !!
