Answer 3

To solve the expression, follow the order of operations (PEMDAS/BODMAS):

1. Parentheses/Brackets
2. Exponents/Orders
3. Multiplication and Division (from left to right)
4. Addition and Subtraction (from left to right)

Let's break down the expression step-by-step:

1. Calculate the value inside the parentheses: 30.7 - 0.6447 ÷ 0.21 = 30.7 - 3.06942857143 (approx) = 27.63057142857 (approx)

2. Perform the multiplication: 101 * 27.63057142857 = 2779.43057142857 (approx)

3. Perform the addition: 9.37 + 2779.43057142857 = 2788.80057142857 (approx)

4. Finally, subtract the last number: 2788.80057142857 - 2008.5 = 779.30057142857 (approx)

Therefore, the result of the expression is approximately 779.30057142857.
