Bonsoir pourriez-vous m’aider svp ex 1, merci

Bonsoir,

Simplifier les nombres suivants afin d’obtenir une fraction la plus simple possible :

A = 10/35

A = (2 x 5)/(7 x 5)

A = 2/7

B = 16/28

B = (4 x 4)/(4 x 7)

B = 4/7

C = 56/72

C = (8 x 7)/(8 x 9)

C = 7/9

D = 110/33

D = (11 x 10)/(11 x 3)

D = 10/3

E = 49/21

E = (7 x 7)/(3 x 7)

E = 7/3

F = 9^2/36

F = (9 x 9)/(9 x 4)

F = 9/4

G = 180/585

G = (5 x 36)/(5 x 117)

G = 36/117

H = 3,2/0,88

H = 320/88

H = (8 x 40)/(8 x 11)

H = 40/11

J = 0,3/18

J = 3/180

J = 3/(3 x 60)

J = 1/60

K = 18,9/6,3

K = 189/63

K = (3 x 63)/63

K = 3

L = 3,2

L = 32/10

L = (2 x 16)/(2 x 5)

L = 16/5

M = -1,76

M = -176/100

M = -(4 x 44)/(4 x 25)

M = -44/25
