What is 0.7 - 5 - 0.125 × 3 + 0.099 - 0.011 approximately calculated to be?

  1. 0.1

  2. 8.6375

  3. -5

  4. -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
