Bonjour :) il faut faire les exercices 33 et 34 svp :) Consigne: calculer et donner les résultats sous forme fractionnaire.

bonsoir

d = 1/4 +1/2 = 1/4 + 1*2 /2*2 = 1/4 +2/4 = 3/4

e = 2/3 -2/9 = 2*3/3*3 -2/9 = 6/9 -2/9 = 4/9

f = 5/6 -10/12 = 5/6 -5/6 = 0

g = 1 +4/5 = 1*5 / 5+4/5 =  95/5 +4/5 = 9/5

h = 2-1/2 = 4/2 -1/2 = 3/2

i = 1/6 +5 = 1/6 + 5*6 /1*6 = 1/6 +30/6 = 31/6
