Answer 2

To solve the expression, let's follow the order of operations (PEMDAS):

P: Parentheses E: Exponents MD: Multiplication and Division (left to right) AS: Addition and Subtraction (left to right)

The expression is:

13.6 - 45:3 (целых) 6 / 13 + 1 (целая) 3 / 8

First, let's deal with the division:

45 ÷ 3 = 15

Now, we have:

13.6 - 15 (целых) 6 / 13 + 1 (целая) 3 / 8

Next, let's handle the multiplication:

15 (целых) 6 = 15 * 6 = 90 1 (целая) 3 = 1 * 3 = 3

The expression becomes:

13.6 - 90 / 13 + 3 / 8

Now, let's perform the division:

90 / 13 ≈ 6.9231 (rounded to 4 decimal places) 3 / 8 = 0.375

The expression becomes:

13.6 - 6.9231 + 0.375

Finally, let's perform the subtraction and addition:

13.6 - 6.9231 ≈ 6.6769 (rounded to 4 decimal places)

6.6769 + 0.375 ≈ 7.0519 (rounded to 4 decimal places)

So, the result of the expression is approximately 7.0519.
