Answer 3

To calculate the expression 40 - (2550 / 204 - 6.9) * 6.7, you should follow the order of operations, which is typically represented by the acronym PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right).

Let's break it down step by step:

1. Inside the parentheses, calculate the division: 2550 / 204 = 12.5

2. Subtract 6.9 from the result: 12.5 - 6.9 = 5.6

3. Multiply the result by 6.7: 5.6 * 6.7 = 37.52

4. Finally, subtract 37.52 from 40: 40 - 37.52 = 2.48

So, the final result is approximately 2.48.
