bonjour
b = 5/10 - 43/100 - 3/10
b = 50/100 - 43/100 - 30/100
b = - 23/100
c = 1/2 + 2/3 + 5/6
c = 3/6 + 4/6 + 5/6
c = 12/6
c = 2
d = - 4/3 - 1/6 + 7/12
d = - 16/12 - 2/12 + 7/12
d = - 11/12
e = 7/6 + 3/2 - 5/4
e = 14/12 + 18/12 - 15/12
e = 17/12
b = 5/10 - 43/100 - 3/10
b = 50/100 - 43/100 - 30/100
b = - 23/100
c = 1/2 + 2/3 + 5/6
c = 3/6 + 4/6 + 5/6
c = 12/6
c = 2
d = - 4/3 - 1/6 + 7/12
d = - 16/12 - 2/12 + 7/12
d = - 11/12
e = 7/6 + 3/2 - 5/4
e = 14/12 + 18/12 - 15/12
e = 17/12
