Bonjour

I = 10/24 + 21/36

I = (2 x 5) / (2 x 12) + (3 x 7) / (3 x 12)

I = 5/12 + 7/12

I = 12/12

I = 1

J = 19/33 - 4/121

J = (19 x 11) / (33 x 11) - (4 x 3) / (121 x 3)

J = 209/363 - 12/363

J = 197/363

K = 11/7 + 7/49 + 6/21

K = (11 x 3) / (7 x 3) + (7 x 1) / (7 x 7) + 6/21

K = 33/21 + 1/7 + 6/21

K = 33/21 + (1 x 3) / (7 x 3) + 6/21

K = 33/21 + 3/21 + 6/21

K = 42/21

K = (21 x 2) / (21 x 1)

K = 2.
