7 / 25 / 2 / 4 / 3 / 3 / 5 / 30 / 8 in descending order
As above

2 / 7 = 120 / 4202 / 5 = 168 / 4203 / 4 = 315 / 4201 / 3 = 140 / 4203 / 5 = 252 / 4208 / 10 = 336 / 420 and 120 ＜ 140 ＜ 168 ＜ 252 ＜ 315 ＜ 336, so 120 / 420 ＜ 140 / 420 ＜ 168 / 420 ＜ 252 / 420 ＜ 315 / 420 ＜ 336 / 420, so 2 / 7 ＜ 1 / 3 ＜ 2 / 5 ＜ 3 / 5 ＜ 3 / 4 ＜ 8 / 10
