Transformer chaque écriture en une fraction irréductible 21sur 9, 0,84sur1,2 39sur52, 17sur51,2,9sur1,45,69sur23,284sur256, 750sur1000, 76sur95,8,8sur22

21/9 = 7/3
0.84/1.2 = 84/120 = 7/10
39/52 = 3/4
17/51 = 1/3
2.9/1.45 = 290/145 = 145
69/23 = 3
284/256 = 71/64
750/1000 = 3/4
75/95 = 15/19
8.8/22 = 88/220 = 2/5
