Answer 2

To solve this expression, 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). Here's the step-by-step calculation:

1. First, calculate the multiplication and division within parentheses/brackets: 17.5 × (5/4) - 0.75 × 17.5 / (10.8 ÷ 0.6) + 36.25

2. Calculate the multiplication inside the first set of parentheses: 17.5 × (5/4) = 21.875

3. Calculate the division inside the second set of parentheses: 10.8 ÷ 0.6 = 18

4. Now, substitute these values back into the original expression: 21.875 - 0.75 × 17.5 / 18 + 36.25

5. Calculate the multiplication: 0.75 × 17.5 = 13.125

6. Perform the division: 13.125 / 18 ≈ 0.72917 (rounded to 5 decimal places)

7. Now, substitute these values back into the expression: 21.875 - 0.72917 + 36.25

8. Finally, perform the remaining additions and subtractions: 21.875 - 0.72917 + 36.25 ≈ 57.39583 (rounded to 5 decimal places)

So, the result of the expression is approximately 57.39583.
