Answer:
3/7,4/9,5/7 and 8/11
Here the LCM of 3,4,5 and 8 is 120
3/7=(3×40)/(7×40)=120/280
4/9=(4×30)/(9×30)=120/270
5/7=(5×24)/(7×24)=120/168
8/11=(8×15)/(11×15)=120/165
So we get
120/165>120/168>120/270>120/280
It can be written as
8/11>5/7>4/9>3/5
Therefore, 8/11,5/7,4/9 and 3/7 are in descending order.
