To simplify this expression, we first need to convert all fractions to a common denominator. The common denominator for 27, 9, 11, and 8 is 297.

14/27 = 140/297
7/9 = 231/297
3/5 = 178/297
1/4 = 74/297
11/27 = 121/297
5/8 = 185/297
40 = 40/1

Now the expression becomes:
140/297 : 231/297, 178/297, 74/297 : 121/297, 185/297 : 40/1

Simplify by cancelling out common factors:
140 : 231, 178, 74 : 121, 185 : 40

The final simplified expression is:
140 : 231, 178, 74 : 121, 185 : 40
