Bonjour à tous qui pourrais m’aider à faire l’exercice 37 merci beaucoup à ceux qui m’aideront

bonjour

A = 5/6 + 2/3

  = 5/6 + 4/6

  = 9 /6 = 3/2

B = 3/4  - 3/16

  = 12/16 - 3 /16

  = 9/16

C = 8/35  - 4/5

  = 8 /35 - 28/35

  = - 20/35

  = - 4 / 7

Bonsoir,

Exercice 37 :

A = 5/6 + 2/3

A = 5/6 + (2×2)/(3×2)

A = 5/6 + 4/6

A = (5+4)/6

A = 9/6

A = 3/2

B = 3/4 + (-3)/16

B = 3/4 - 3/16

B = (3×4)/(4×4) - 3/16

B = 12/16 - 3/16

B = (12-3)/16

B = 9/16

C = 8/35 + (-4)/5

C = 8/35 - 4/5

C = 8/35 - (4×7)/(5×7)

C = 8/35 - 28/35

C = (8-28)/35

C = -20/35

C = -4/7

Bonne soirée !
