Пошаговое объяснение:

19,142 : 3,4 + 6,72 * 3,5 - 0,81 : 0,9 = 5,63 + 6,72 * 3,5 - 0,81 : 0,9 = 5,63 + 23,52 - 0,81 : 0,9 = 5,63 + 23,52 - 0,9 = 28,25

Answer 2

To solve the expression, we'll follow the order of operations: parentheses, multiplication and division (from left to right), and addition and subtraction (from left to right).

19,142 : 3,4 + 6,72 × 3,5 - 0,81 ÷ 0,9

First, let's perform the division and multiplication:

1. 19,142 ÷ 3,4 ≈ 5,63647 (rounded to 5 decimal places)
2. 6,72 × 3,5 = 23,52
3. 0,81 ÷ 0,9 = 0,9

Now the expression becomes:

5,63647 + 23,52 - 0,9

Next, add and subtract:

1. 5,63647 + 23,52 ≈ 29,15647 (rounded to 5 decimal places)
2. 29,15647 - 0,9 ≈ 28,25647 (rounded to 5 decimal places)

So, the final result is approximately 28.25647.
