Bonjour pouvez vous m’aider svp ? (:

Bonsoir,

E=-7/5÷(6+1/5)

E=-7/5÷(30/5+1/5)

E=-7/5÷31/5

E=-7/5*5/31

E=-7/31

F=3/4÷7/8-3/7

F=3/4*8/7-3/7

F=6/7-3/7

F=3/7

G=(3/2-1/4)÷(2-1/2)

G=(6/4-1/4)÷(4/2-1/2)

G=5/4÷3/2

G=5/4*2/3

G=10/12

G=5/6

Bonsoir c'est si simple que tu le penses

E=-7/5÷(6+1/5)

E=-7/5÷(30/5+1/5)

=-7/5÷31/5

=-7/5*5/31

=-7/31

F=3/4÷7/8-3/7

=3/4*8/7-3/7

=6/7-3/7

=3/7

G=(3/2-1/4)÷(2-1/2)

=(6/4-1/4)÷(4/2-1/2)

=5/4÷3/2

=5/4*2/3

=10/12

=5/6

Bonne soirée
