Answer 2

To solve this expression, let's break it down step by step:

1. Simplify the expression inside the parentheses:

   (-9,7 + 7,1) = -2.6

   This is because (-9.7 + 7.1) = -2.6

2. Simplify the expression inside the absolute value:

   |-3.45| = 3.45

   This is because the absolute value of a number is the distance of that number from zero on the number line.

3. Simplify the expression inside the denominator:

   (-1/4) + (9) = 35/4

   This is because -1/4 + 9 = 35/4

Now, we have:

-2.6 ÷ (35/4) ÷ 3.45

Next, let's simplify further:

-2.6 ÷ (35/4) ÷ 3.45

-2.6 ÷ (8.75) ÷ 3.45

-0.29714285714 ÷ 3.45

-0.08615128058

So, (-9.7 + 7.1) : (-1/4 + 9) + |-3.45| simplifies to approximately -0.086.
