Answer 2

To solve the expression 0.351:12.7 + 3.05 * (13.9 - 1.72), 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).

Let's break it down step by step:

1. Start with the expression inside the parentheses: (13.9 - 1.72) = 12.18

Now the expression becomes: 0.351 / 12.7 + 3.05 * 12.18

2. Perform the division: 0.351 / 12.7 ≈ 0.0276378 (rounded to 7 decimal places)

Now the expression becomes: 0.0276378 + 3.05 * 12.18

3. Perform the multiplication: 3.05 * 12.18 ≈ 37.169 (rounded to 3 decimal places)

Now the expression becomes: 0.0276378 + 37.169

4. Finally, add the two results together:

0.0276378 + 37.169 ≈ 37.196 (rounded to 3 decimal places)

So, the result of the expression is approximately 37.196.
