Bonjour
Calculer.
F= 11/6 - (-3/4 - 5/6)
F = 11/6 - [(-3 x 3)/(4 x 3) - (5 x 2)/(6 x 2)]
F = 11/6 - (-9/12 - 10/12)
F = 11/6 - (-19/12)
F = (11 x 2)/(6 x 2) + 19/12
F = 22/12 + 19/12
F = 41/12
G= (4/21 - 3/7) - (3/10 - 8/15)
G = (4/21 - (3 x 3)/(7 x 3)) - [(3 x 3)/(10 x 3) - (8 x 2)/(15 x 2)]
G = (4/21 - 9/21) - (9/30 - 16/30)
G = (-5/21) - (-7/30)
G = (-5/21) + 7/30
G = (-5 x 10)/(21 x 10) + (7 x 7)/(30 x 7)
G = (-50/210) + 49/210
G = (-1/210)
