------------
Yes, find the LCD, then reformulate each number.
LCD of 3,11,9,2
---
LCD = 2*9*11 = 198
----
2 = 396/198
---
2 6/11 = 28/11 = (2*9*28)/198 = 504/198
---
2 5/9 = 23/9 = (2*11*23)/198 = 506/198
---
2 1/2 = 5/2 = (9*11*5)/198 = 495/198

THE DECIMAL SYSTEM:
2 2/3=2.66
2 6/11=2.5454
2 5/9=2.555
2 1/2=2.5
GREATEST TO LEAST:
2 2/3
2 5/9
2 6/11
2 1/2
--------------------------
THE FRACTION SYSTEM:
8/3, 28/11, 23/9, 5/2
LCD=11*9*2=198
66*8/198=528/198
18*28/198=504/198
22*23/198=506/198
99*5/198=495/198
GREATEST TO LOWEST:
528/198, 506/198, 504/198, 495/198
