Bonjour,

A = 4/11 + 3/11

A = 7/11

B = 1/6 + 5/3
B = 1/6 + 10/6

B = 11/6

C = 1/4 - 3/28
C = (1 x 7)/(4 x 7) - 3/28

C = 7/28 - 3/28

C = 4/28

C = (4 x 1)/(4 x 7)

C = 1/7

D = -19/14 + (1/7 + 2)

D = -19/14 + (1/7 + 2/1)

D = -19/14 + (1/7 + 14/7)

D = -19/14 + 15/7

D = -19/14 + 30/14
D = 11/14
