merci à celle ou celui qui arrivera à m'aider sur cette exercice ​

A = 2 + ( 8 / ( 171 / 19 + 5 / 19 )

A = 2 + ( 8 / (176 / 19))

A = 2 + ( 8 x 19 / 1 x 176 )

A = 2 + ( 152 / 176 )

A = 352 / 176 + 152 / 176

A = 504 / 176

A = 126 / 44

A = 63 / 22

B = 1 + ( 3/24 + 18/24 - 2/24) / (10/12 + 4/12 + 24/12)

B = 1 + ( 19/24 ) / (38/12)

B = 1 + (19x12) / (24x38)

B = 1 + (228/912)

B = 912 / 912 + 228 / 912

B = 1140 / 912

B = 190 / 152

B = 95 / 76

B = 5/4

C = 5/12 / (56/45 - 5/6)

C = 5/12 / (112/90 - 75/90)

C = 5/12 / 37/90

C = (5x90) / (12x37)

C = 450 / 444

C = 75 / 74
