Calculer les expressions suivantes :
A = 1/5 + 6/5 = 7/5
B = 26/34) - 16/34 = 10/34 = 5/17
C = 1/2 + 2/6 = 3/6 + 2/6 = 5/6
D = 4/15 + 3/5 = 4/15 + 9/15 = 13/15
E = 5/14 - 2/7 = 5/14 - 4/14 = 1/14
F = 2 + 3/5 = 10/5 + 3/5 = 13/5

Bonjour !
A = 1/5+6/5 = 7/5
B = 26/34-16/34 = 10/34 = 5/17
C = 1/2+2/6 = 1×3/2×3+2/6=3/6+2/6=5/6
D = 4/15+3/5= 4/15+3×3/5×3 = 4/15+9/15
D = 13/15
E = 5/14-2/7= 5/14-2×2/7×2 = 5/14-4/14
E = 5/14 - 4/14 = 1/14
F = 2+3/5 = 2×5/5 + 3/5 = 10/5+3/5=13/5
Bonne journée.
