Bonsoir,

A = 4/5 : 7/3

A = 4/5 x 3/7

A = (4 x 3)/(5 x 7)

A = 12/35

B = 3/7 : 5/11

B = 3/7 x 11/5

B = (3 x 11)/(7 x 5)

B = 33/35

C = 5/7 : 3/2

C = 5/7 x 2/3

C = (5 x 2)/(7 x 3)

C = 10/21

D = 1/3 : 3/7

D = 1/3 x 7/3

D = (1 x 7)/(3 x 3)

D = 7/9

E = 5/3 : 2/7

E = 5/3 x 7/2

E = (5 x 7)/(2 x 3)

E = 35/6

F = 3/7 : 5/3

F = 3/7 x 3/5

F = (3 x 3)/(7 x 5)

F = 9/35

G = 7/9 : 1/3

G = 7/9 x 3

G = (7 x 3)/(3 x 3)

G = 7/3

H = 4/9 : 2/5

H = 4/9 x 5/2

H = 4/2 x 5/9

H = (2 x 2)/2 x 5/9

H = 2 x 5/9

H = 10/9

I = 6 : 3/7

I = 6 x 7/3

I = (2 x 3 x 7)/3

I = 14

J = 2 : 5/3

J = 2 x 3/5

J = 6/5

K = 2/3 : 5

K = 2/3 x 1/5

K = (2 x 1)/(3 x 5)

K = 2/15

L = 3 : 2/5

L = 3 x 5/2

L = 15/2
