A = (4/8 + 2/8 + 1/8) x 4 = 7/8 x 4 = 3,5
B = 4/18 - 1/2 + 91/36 = 8/36 - 18/36 + 91/36 - tu finis
C = 24/24 + 8/24 + 3/24 + 2/24 + 1/24 tu finis
D = 11/70 - 6/84 = 924/5880 - 420/5880 - tu finis

Salut ;
105 :
A= (1/2 + 1/4 + 1/8) x4 B= 4/18 - 1/2 + 91/36
=4/2 +4/4+4/8 = 8/36 + 91/36 -1/2
=2 +1 +1/2 =99/36 -1/2
=3+1/2 = 198/72 - 36/72
=3/1 + 1/2 =162/72
=6/2 +1/2 = 81/36
=7/2
106 :
C = 1 + 1/3 + 1/6+ 1/12 + 1/24 D= 11/70 - 6/84
=4/3 + 1/6+ 1/12+1/24 = 11x84/70x84 - 6x70/84x70
=9/6 + 1/12+ 1/24 =924/5880 - 420/5880
=18/12 + 1/12 + 1/24 = 504/5880 = 126/1470 =63/735
= 19/12 + 1/24 = 39/24 = 21/245
= 3/35
