Answer 2

It looks like you've provided a mathematical expression in Russian. Let's break it down step by step.

First, let's translate the expression into a more readable format: 2 ÷ 1/4 * [(1 + 1/2 + 2 + 2/3) ÷ 3 + 3/4 - 2/3] ÷ 8 + 8/9

Now, let's solve the expression step by step:

Step 1: Evaluate the innermost parentheses

1 + 1/2 + 2 + 2/3 = (6/6) + (3/6) + (12/6) + (4/6) = 25/6

Step 2: Evaluate the expression inside the brackets

(25/6) ÷ 3 + 3/4 - 2/3 = (25/6) ÷ 3 + 9/12 - 8/12 = (25/18) + 1/12 = (25/18) + (3/18) = 28/18

Step 3: Evaluate the expression within the brackets

2 ÷ 1/4 * (28/18) ÷ 8 + 8/9 = 2 ÷ 4 * (28/18) ÷ 8 + 8/9 = 2 * 4 * (28/18) ÷ 8 + 8/9 = 8 * (28/18) ÷ 8 + 8/9 = (224/18) ÷ 8 + 8/9 = 224/144 + 8/9 = 56/36 + 32/36 = 88/36 = 11/4

Final Answer:

The value of the given expression is 11/4.
