bonjour
D = 11/12 + 21/12 = 32/12 = 8/3
E = 5/21 + 1/14 = 10/42 + 3/42 = 13/42
a = 40/90 - 90/90 = 130/90 = 13/9
b = 21/36 - 20/36 = 1/36
c = 10/75 - 18/75 = - 8/75
d = 5/5 - 7/5 = - 2/5
e = 22/90 + 21/90 = 43/90 -

D= 11/12 +7x3/4x3
D= 11/12 + 21/12
D= 32/12
D= 8/3
E= 5/21 + 1/14
E= 5x2/21x2 + 1x3/14x3
E= 10/42 + 3/42
E= 13/42
