Вот решение. Клавиатура не может написать решение в столбик, поэтому я приложила фото. Думаю мой подчерк понятен.

Answer 2

To solve this expression, you should follow the order of operations (PEMDAS/BODMAS - Parentheses/Brackets, Exponents/Orders, Multiplication and Division, Addition and Subtraction) and work from left to right:

1. 49.52 × 0.1 = 4.952
2. 12.5 × 4.87 = 60.875
3. 5.8 ÷ 0.01 = 580
4. 0.5 ÷ 100 = 0.005
5. 55.04 ÷ 3.2 = 17.2

Now, let's multiply and divide these results as per the original expression:

4.952 × 60.875 ÷ 580 × 0.005 ÷ 17.2

Let's calculate this step by step:

1. 4.952 × 60.875 = 301.372
2. 301.372 ÷ 580 = 0.51963448 (approximately, rounded to 8 decimal places)
3. 0.51963448 × 0.005 = 0.00259817 (approximately, rounded to 8 decimal places)
4. 0.00259817 ÷ 17.2 = 0.00015096 (approximately, rounded to 8 decimal places)

So, the final result is approximately 0.00015096.
