Пошаговое объяснение:

Answer 2

To solve this expression, you should follow the order of operations, which is typically remembered using the acronym PEMDAS:

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

Let's solve your expression step by step:

1. First, perform the operations inside the parentheses: 3 2/5 + 1 3/5 = 3.4 + 1.6 = 5

2. Now, the expression becomes: 2.6 × 3.5 - 18 ÷ 5

3. Next, perform the multiplication and division from left to right: 2.6 × 3.5 = 9.1 18 ÷ 5 = 3.6

4. Now, the expression becomes: 9.1 - 3.6

5. Finally, perform the subtraction: 9.1 - 3.6 = 5.5

So, the final result of the expression is 5.5.
