Bonsoir pouvez vous m’aidez svp je suis en 5 eme exercice 2 merci

Bonsoir,

A = 7/32 + 10/4

A = 7/32 + (10 x 8) / (4 x 8)

A = 7/32 + 80/32

A = 87/32

B = 2/2 - 2/9

B = 1 - 2/9

B = (1 x 9) / (1 x 9) - 2/9

B = 9/9 - 2/9

B = 7/9

C = 2/4 + 1

C = 2/4 + (1 x 4) / (1 x 4)

C = 2/4 + 4/4

C = 6/4

C = (2 x 3)/ (2 x 2)

C = 3/2

D = 8/6 + 8/8

D = (2 x 4) / (2 x 3) + 1

D = 4/3 + (1 x 3) / (1 x 3)

D = 4/3 + 3/3

D = 7/3

E = 4 - 2/2

E = 4 - 1

E = 3

F = 2/4 + 4/4

F = 1/2 + 1

F = 1/2 + (1 x 2) / (1 x 2)

F = 1/2 + 2/2

F = 3/2
