Voila j aimerai avoir de l aide pour la question qui suit svp merci 24/35-[(3/5-9/7)]/2-(11/4)

A= 24/35 _ [ (3/5 - 7/9) ] / 2 _ (11/4)
= 24/35 _ [ 27/45 - 35/45 ] / 2 _ (11/4)
= 24/35 _ ( -8/45) / 2 ) _ (11/4)
= 24/35 _ ( -4/45) _ 11/4
= 24/35 + 4/45 _ 11/4
=1220/1575 _ 11/45
=37575 / 70875
= 167/315.
