Bonsoir,

A = -6/5 * 8/3 = -48/15 = -16/5

B = 7/-4 ÷ -5/8 = 7/-4 * 8/-5 = 56/-20 = 14/-5

C = -25/49 * -21/15 = -25/49 * -7/5 = 175/245 = 35/49 = 5/7

D = Tu essaies ? :)

Exercice 3 :

E = -5/7 + 2/7 * 14/5

E = -5/7 + 28/35

E = -25/35 + 28/35

E = 3/35

F = ( 9/5 + 1 ) ÷ (3/2 - 3/4)

F = (9/5 + 5/5) ÷ (6/4 - 3/4)

F = 14/5 ÷ 3/4 = 14/5 × 4/3

F = 56/15
