pouvez vous faire les 4 calcul svp​

Bonsoir,

E=

3/6 -1/6 = 2/6 = 1/3

F=

-12/24 -1/2 = -1/2 -1/2 = -2/2 = -1

G=

4/7 * (1/4 +6/4)

= 4/7 * 7/4

= 28/4

= 7

H=

28/5 * ( 2/14 -7/14)

= 28/5 * -5/14

= -140/ 70

= - 2

Bonjour

Explications étape par étape :

E = 3/6 - 1/2 X 1/3

E = 3/6 -1/6

E = 2/6 = 1/3

F = 3/4 X -4/6 -1/2

F = -12/24 - 1/2 X 12/12

F = -12/24 -12/24

F = -24/24 = -1

G = 4/7 X (1/4 + 3/2)

G = 4/7 X ( 1/4 + 3/2 X 2/2)

G = 4/7 X (1/4 + 6/4)

G = 4/7 X 7/4

G = 28/28 = 1

G = 28/5 X ( 1/7 -1/2)

G = 28/5 X ( 1/7 X 2/2 -1/2 X 7/7)

G = 28/5 X (2/14 -7/14)

G = 28/5 X -5/14

G = -140/70 = -14/7 = -2
