Answer 3

To solve this expression, you should follow the order of operations (PEMDAS/BODMAS), which stands for Parentheses/Brackets, Exponents/Orders (i.e., powers and square roots, etc.), Multiplication and Division (left-to-right), and Addition and Subtraction (left-to-right).

In your expression:

(87 - 68.4) * 4.5 + 58.8 / 5.6

Let's break it down step by step:

1. Calculate the subtraction inside the parentheses: 87 - 68.4 = 18.6

2. Multiply the result by 4.5: 18.6 * 4.5 = 83.7

3. Divide 58.8 by 5.6: 58.8 / 5.6 ≈ 10.5

4. Add the result of the division to the previous result from multiplication: 83.7 + 10.5 = 94.2

So, the final result is approximately 94.2.
