Explications étape par étape

Bonjour

Recopier et compléter :

-5/... = .../30 = 45/... = 10/-12 = -15/...

10/-12 = -(2 x 5)/(2 x 6) = -5/6

-5/6 = (-5 x 5)/(6 x 5) = -25/30

-5/6 = (-5 x -9)/(6 x -9) = 45/-54

-5/6 = (-5 x 3)/(6 x 3) = -15/18

-5/6 = -25/30 = 45/-54 = 10/-12 = -15/18

6) recopier et compléter :

a) -28/35 = (-4 x 7)/(5 x 7) = -4/5

b) 40/48 = (8 x 5)/(8 x 6) = 5/6

c) -63/-49 = (9 x -7)/(7 x -7) = 9/7
