bonjour
A = 37/5 = 35/5 + 2 /5 = 7 + 2 /5
B = 34/3 = 33/3 + 1/3 = 11 + 1 /3
C = 51/4 = 48/4 + 3/4 = 12 + 3 /4
A + B = 35/7 + 34/3 = 105/21 + 238/21 = 343 /21 = 49/3
C - B = 51/4 - 34/3 = 153/12 - 136 /12 = 17/12
A + C = 37/5 + 51/4 = 148/20 + 255/20 = 403/20
7/20 + 1/20 = 8/20 = 2/5
1/4 + 1/5 = 5/20 + 4/20 = 9 /20
musculation = 1 - ( 2/5 + 9/20 ) = 20/20 - ( 8/20 + 9/20 )
= 20/20 - 17/20 = 3 /20
