j’ai besoin d’aide s’il vous plaît ​

Bonjour !

1)

-2/3 = (-2*10)/(3*10) = -20/30

1/6 = (1*5)/(6*5) = 5/30

4/5 = (4*6)/(5*6) = 24/30

2)

-3/24 = (-3*2)/(24*2) = -6/48

3/4 = (3*12)/(4*12) = 36/48

-3/8 = (-3*6)/(8*6) = -18/48

3)

-32/12 = (-32*24)/(12*24) = -768/288

-24/18 = (-24*16)/(18*16) = -384/288

4/32 = (4*9)/(32*9) = 36/288

4)

-1/24

1/8 = 3/24

-1/3 = -8/24

1/2 = 12/24

Bon courage !
