Answer 2

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 this expression, there are no exponents or square roots, so we'll start with multiplication and division within parentheses and then perform the final division.

Let's break it down step by step:

1. Inside the first set of parentheses: 9.2 + 27 1/4 = 9.2 + 27.25 (convert the mixed number to a decimal) = 36.45

2. Inside the second set of parentheses: 18 3/25 - 9.88 = 18.12 - 9.88 (convert the mixed number to a decimal) = 8.24

3. Now, we have: 10 × (36.45) : 54 × (8.24) : 927 × 2.5

4. Perform the multiplications within each set of parentheses: 10 × 36.45 = 364.5 54 × 8.24 = 444.96

5. Now the expression becomes: 364.5 : 444.96 : 927 × 2.5

6. Perform the divisions from left to right: 364.5 ÷ 444.96 ≈ 0.8195 (rounded to four decimal places) 0.8195 : 927 × 2.5

7. Finally, perform the remaining multiplication: 0.8195 × 927 × 2.5 ≈ 1913.92 (rounded to two decimal places)

So, the final result is approximately 1913.92.
