Answer 2

It seems like you've provided a mathematical expression that needs to be evaluated. Let's break it down step by step:

Expression: 20:(6--3-11+1--8-11)+(7---2-5-5'8):5

First, let's simplify the terms involving subtraction: 6--3 = 6 + 3 = 9 1--8 = 1 + 8 = 9 7---2 = 7 + 2 = 9 5'8 = 5.8 (assuming the apostrophe is a decimal point)

Now, the expression becomes: 20:(9-11+9-5.8):5

Continue simplifying: 9 - 11 = -2 9 - 5.8 ≈ 3.2

The expression now becomes: 20:(-2+3.2):5

Simplify further: -2 + 3.2 ≈ 1.2

The expression becomes: 20:1.2:5

Divide 20 by 1.2: 20 / 1.2 ≈ 16.67

Finally, divide 16.67 by 5: 16.67 / 5 ≈ 3.33

So, the value of the given expression is approximately 3.33.
