Answer 2

To calculate the expression, let's follow the order of operations (PEMDAS/BODMAS):

1. Parentheses/Brackets
2. Exponents/Orders
3. Multiplication and Division (from left to right)
4. Addition and Subtraction (from left to right)

The expression is: (3,04:1/30-16,03:7/20) * 1/5 + 0,072 * 1/3

Let's first address the comma in the numbers. In some countries, a comma is used as a decimal separator, while in others, it's a period. For the purpose of this calculation, I'll assume that a comma represents a decimal point:

(3.04 - 16.03) * (1/30 - 7/20) * (1/5) + (0.072 * 1/3)

Now, perform the calculations step by step:

1. Calculate the values inside the parentheses: (3.04 - 16.03) = -12.99 (1/30 - 7/20) = (2/60 - 21/60) = -19/60

2. Calculate the multiplication inside the first set of parentheses: -12.99 * (-19/60) = 12.99 * 19/60 = 12.99 * 19 / 60 = 259.81 / 60 ≈ 4.33016667

3. Calculate the multiplication and division from left to right: 4.33016667 * (1/5) = 4.33016667 / 5 ≈ 0.8660333334

4. Calculate the second term: 0.072 * (1/3) = 0.072 / 3 = 0.024

5. Finally, add the results of step 3 and step 4: 0.8660333334 + 0.024 ≈ 0.8900333334

So, the result of the expression is approximately 0.890.
