Bonjour

A = 2/3 : 4

A = 2/3 x 1/4

A = 2/12

A = (2 x 1) / (2 x 6)

A = 1/6

B = 2 : 3/4

B = 2 x 4/3

B = 8/3

C = (1/2 - 1/4) : 1/4

C = [(1 x 2) / (2 x 2) - 1/4] : 1/4

C = (2/4 - 1/4) : 1/4

C = 1/4 : 1/4

C = 1/4 x 4

C = 4/4

C = 1

D = (2/3 - 1) : (2/3 + 1)

D = [2/3 - (1 x 3) / (1 x 3)] : [2/3 + (1 x 3) / (1 x 3)]

D = (2/3 - 3/3) : (2/3 + 3/3)

D = - 1/3 : 5/3

D = - 1/3 x 3/5

D = - 3/15

D = (3 x - 1) / (3 x 5)

D = - 1/5.
