Bonjour je n’arrive pas à calculer cette exercice merci de bien vouloir m’aider !❤️

Bonjour,

A = 4/3 + 1/7 x 3/2

A = 4/3 + 3/14

A = (4 x 14) / (3 x 14) + (3 x 3) / (14 x 3)

A = 56/42 + 9/42

A = 65/42

B = (4 - 5/2) : (7/3 + 3/2)

B = [4 x 2) / (1 x 2) - 5/2] : [(7 x 2) / (3 x 2) + (3 x 3) / (2 x 3)]

B = (8/2 - 5/2) : (14/6 + 9/6)

B = 3/2 : 23/6

B = 3/2 x 6/23

B = 18/46

B = (2 x 9) / (2 x 23)

B = 9/23.
