Exercice 2 SVP??? A=2/3 - 5/13 : 10/16 B =3-2/3 / 4/3 x7

Bonjour,

A=2/3 - 5/13 : 10/16

A = 2/3 - 5/13 x 16/10

A = 2/3 - 5/10 x 16/13

A = 2/3 - 1/2 x 16/13

A = 2/3 - 16/2 x 1/13

A = 2/3 - 8 x 1/13

A = 26/39 - 24/39

A = 2/39

B =3-2/3 / 4/3 x7

B = (3 - 2/3) / (4/3 x 7)

B = (9/3 - 2/3) / (28/3)

B = 7/3 x 3/28

B = 7/28 x 3/3

B = 1/4
