To simplify the given expression, we will follow the order of operations (PEMDAS/BODMAS):

Start with the parentheses:
1/2 + (1.5:3 ∙ 3/4) ∙ 2 - (1 + 23/49):22/147/2 : 3 + (3.25:13):2/3 - (2.27 - 0.472) ∙ 0.276

Perform division within the parentheses:
1/2 + (0.5 ∙ 0.75) ∙ 2 - (1 + 23/49):22/147/2 : 3 + (0.25:13):2/3 - (2.27 - 0.472) ∙ 0.276

Simplify the division:
1/2 + (0.375) ∙ 2 - (1 + 0.469):22/147/2 : 3 + (0.0192):2/3 - (2.27 - 0.472) ∙ 0.276

Solve the multiplication:
1/2 + 0.75 - (1 + 0.469):22/147/2 : 3 + 0.0096 - (2.27 - 0.472) ∙ 0.276

Perform addition and subtraction:
1/2 + 0.75 - (1 + 0.469):22/147/2 : 3 + 0.0096 - 1.7986 ∙ 0.276

Calculate within the parentheses:
1/2 + 0.75 - 1.469:0.1506 : 3 + 0.0096 - 0.495198

Perform division:
0.5 + 0.75 - 1.469 : 0.048209 : 3 + 0.0096 - 0.495198

Simplify the division operation:
0.5 + 0.75 - 30.418313479 : 3 + 0.0096 - 0.495198

Perform subtraction:
0.5 + 0.75 - 30.418313479 : 3. + 0.0096 - 0.495198

Calculate the final result:
0.5 + 0.75 - 10.139437826 + 0.0096 - 0.495198
1.25 - 10.139437826 + 0.0096 - 0.495198
-8.375035226

Therefore, the simplified result of the given expression is approximately -8.375.
