(g= 7/3)

h= 3/7 + 17/14 - 23/28
h= 6/14 + 17/14 -23/28
h=23/14 - 23/28
h= 46/28 - 23/28

Réponse :

G = (7/6) x (7/2 -3/2) = (7/6) x ((7-3)/2)

G = (7/6) x (4/2) = (7/(2x3)) x 2

G = 7/3

H = 3/7 + 17/14 -23/18  

H = 3*18 + 17*9 -23*7 / (7*18) = (54 +153 -161) /126

H = 46/126= 23 / 63

j'espère avoir aidé
