Bonjour

18/16 = (2 x 9) / (2 x 8) = 9/8

4/10 = (2 x 2) / (2 x 5) = 2/5

30/45 = (15 x 2) / (15 x 3) = 2/3

12/24 = (12 x 1)  / (12 x 2) = 1/2

27/36 = (9 x 3) / (9 x 4) = 3/4

70/20 = (10 x 7) / (10 x 2) = 7/2

14/42 = (14 x 1) / (14 x 3) = 1/3

28/70 = (14 x 2) / (14 x 5) = 2/5

35/49 = (7 x 5) / (7 x 7) = 5/7

63/42 = (21 x 3) / (21 x 2) = 3/2

84/77 = (7 x 12) / (7 x 11) = 12/11

15/60 = (15  x 1) / (15 x 4) = 1/4

26/52 = (26 x 1) / (26 x 2) = 1/2

51/68 = (17 x 3) / (17 x 4) = 3/4

252/189 = (63 x 4) / (63 x 3) = 4/3.
