B= -(3/4-5/6)-(3/2-5/12) = -(9/12-10/12) -(18/12-5/12) =-(-1/12) -(13/12) = 1/12-13/12 = -12/12 = -1
C= 1/3-(8/9-1/2)-(-5/6) = 1/3 -(16/18-9/18) + 5/6 = 1/3-7/18 +5/6 = 6/18-7/18+15/18 =14/18 =7/9
D=25/4*2/15-3/2 = 50/60-3/2 = 5/6-3/2 = 5/6-9/6 = -4/6 = -2/3
E= 15/27*6/25-3/10 = 90/675 -3/10 =14/135 -3/10 je te laisse faire la suite .....
F= 1/2-(4/5-1/4)-(-3/10) = 1/2 -(16/20-5/20) +3/10 idem je te laisse calculer la suite
