Calculate the value of the expression: [ (3/7) × {21 × (33.33% of (27 + 3) divided by 5) minus 7} minus 8 ] = ?

Explanation

Let's simplify step-by-step: First, calculate inside the parentheses: 27 + 3 = 30. Next, find 33.33% of 30, which is approximately 1/3 of 30 = 10. Divide 10 by 5 to get 2. Multiply 21 by 2 to get 42. Subtract 7 from 42, resulting in 35. Multiply 35 by 3/7, which equals 15. Finally, subtract 8 from 15, giving the result 7.
