To solve this expression, we will first simplify each fraction separately:
18 5/12 = (12*18 + 5)/12 = 221/12
7/12 = 7/12
119/21 = 119/21
17/72 = 17/72
2/3 = 2/3
Now, we will multiply the fractions together:
(221/12) (7/12) (119/21) (17/72) (2/3)= (221 7 119 17 2) / (12 12 21 72 3)= 8921758 / 54432= 1638879/9984
Therefore, the simplified expression is 1638879/9984.

= (221 7 119 17 2) / (12 12 21 72 3)
= 8921758 / 54432
= 1638879/9984
Therefore, the simplified expression is 1638879/9984.
