Question

_ 2      2   -- : (  -- ) (в начале минус)    7      3​

Answer 1

-(2/7):(2/3)=-(2/7)*(3/2)=-(2*3)/ (7*2)= -6/14=- 3/7 -ответ

Answer 2

It seems like you've provided a string of characters that appears to represent a mathematical expression. Let's break it down step by step:

_ 2 --> This part is unclear. It's just an underscore followed by the number 2. Without context, it's not clear what this means.

2 --> This is a number 2.

-- --> This appears to be a double dash, which typically represents subtraction.

: --> This is a colon, which might indicate that what follows is a definition or a condition.

( --> An opening parenthesis.

  --> This is an HTML entity for a non-breaking space. It doesn't have any specific mathematical significance.

-- --> Another double dash, representing subtraction.

) --> A closing parenthesis.

  --> Another non-breaking space.

-- --> Yet another double dash, representing subtraction.

  --> Another non-breaking space.

7 --> This is the number 7.

  --> Another non-breaking space.

3 --> This is the number 3.

​ --> This is an invisible character, which doesn't have any mathematical significance.

It's challenging to interpret the expression as a whole without more context or clarification on the meaning of the underscore (_) and colons (:). Additionally, the use of non-breaking spaces and invisible characters makes it even more confusing.

If you can provide more context or clarify the expression's purpose, I'd be happy to help you understand it better or perform any calculations involved.
