0.1
8.6375
-5
-5.1

The correct answer is: 8.6375

To determine the correct answer, it's important to accurately perform the arithmetic operations as per the order of operations (PEMDAS/BODMAS: Parentheses/Brackets, Exponents/Orders, Multiplication and Division (from left to right), Addition and Subtraction (from left to right)). First, let's break down the operations step-by-step: 1. **Multiply**: Start with the multiplication operation. Calculate $0.125 \times 3$, which equals $0.375$. 2. **Insert into the equation**: Now, substitute back into the equation: \[ 0.7 - 5 - 0.375 + 0.099 - 0.011 \] 3. **Subtraction and Addition**: Proceed from left to right. - Start with $0.7 - 5$ which equals $-4.3$. - Next, $-4.3 - 0.375$ results in $-4.675$. - Add $0.099$ to $-4.675$, yielding $-4.576$. - Finally, subtract $0.011$ from
