Bonjour
A = 1/2 - 1/3 + 1/4 = 6/12 - 4/12 + 3/12 = 5/12
B = 2 - 13/7 + ( 1 + 5/2)
B = 2 - 13/7 + ( 2/2 + 5/2)
B = 2 - 13/7 + 7/7
B = 14/7 - 13/7 + 7/7 = 8/7
c = (2/3 - 3/4) + 3 ( 4/5 - 5/6)
C = ( 8/12 - 9/12) + 3 ( 24/30 - 25/30)
C = - 1/12 + 3 ( - 1/30)
C = - 1/12 - 3/30
C = - 5/60 - 6/60
C = - 11/60
D = (1/2 +5/3) x ( 3 -7/4) : (1/2 - 5/6)
D = ( 3/6 + 10/6) x ( 12/4 - 7/4) : ( 3/6 - 5/6)
d = 13/6 x 5/4 : - 2/6
d = 13/6 x 5/4 x - 6/2
d = - 390/48 = - 65/8
E = (2/3 + 1/4 - 1/5 x 3/4) : ( 2/5 x 4/3 + 1/3)
E = ( 2/3 + 1/4 - 3/20) : ( 8/15 + 1/3)
E = (40/60 + 15/60 - 9/60) : ( 8/15 + 5/15)
E = 46/60 : 13/15
E = 46/60 x 15/13
E = 690/780 = 23/26
