Пошаговое объяснение:

0.213:0.426+8.2-8.2:(8.7-4.6)= -1

1)8,7-4,6=4,1

2)0.213:0.426= 0,5

3) 8,2: 4,1=2

4) 0,5+8,5=1

5) 1-2= -1

Answer 2

To solve this expression, you should 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 innermost parentheses: 8.7 - 4.6 = 4.1

2. Replace the innermost parentheses with the result: 0.213 : 0.426 + 8.2 - 8.2 : 4.1

3. Now, perform the divisions from left to right: 0.213 ÷ 0.426 = 0.5 (rounded to one decimal place) 8.2 ÷ 4.1 = 2.0

4. Replace the divisions with the results: 0.5 + 2.0 - 8.2 : 4.1

5. Perform the remaining operations from left to right: 0.5 + 2.0 = 2.5 8.2 ÷ 4.1 = 2.0

6. Finally, subtract: 2.5 - 2.0 = 0.5

So, the final result is 0.5.
