Question

2) 1:1 + 1 + 1 (1 + 1:1-1) - 1 - 1 - 1 : (1 + 11 - 1)​

Answer 1

Ответ:

1)

1:1=1;

(1+1:1-1)=1;

(1+11-1)=11;

2)

1+1+1=3-1-1-1=0:11=0

Answer 2

Let's break down the expression step by step:

1:1 = 1 (It's just a ratio, and the ratio of 1:1 simplifies to 1.) 1 + 1 = 2 1 + 1:1 - 1 = 1 + 1 - 1 = 1 (Again, 1:1 is 1, so this simplifies to 1.) 1 - 1 - 1 = -1 1 + 11 - 1 = 11 1 : (11) = 1/11

Now putting it all together:

1 + 2 + 1 - (-1) - 1/11

Simplify the negatives:

1 + 2 + 1 + 1 + 1/11

Combine the whole numbers:

5 + 1/11

So, the final result of the expression is approximately 5.090909 (when the fraction is converted to a decimal).
