2. (i)15/17 and 20/24

LCM=408

15/17×24/24=360/408

20/24×17/17=340/408

360/408>340/408

i.e, 15/17>20/24

(ii)70/105 and 85/205

LCM=4305

70/105×41/41=2870/4305

85/205×21/21=1785/4305

2870/4305>1785/4305

i.e, 70/105>85/205

3. (i)3/5,4/7,8/9

180/315<189/315<280/315

i.e, 4/7<3/5<8/9

(ii)12/15,14/18,21/24=3/5,7/9,7/8

LCM=360

3/5×72/72=216/360
