Answer 3

It seems there might be some confusion in the way the expression is written. Let's break it down step by step and simplify it:

The given expression: (-1/1/9) × (1/3/5 - 1=4) + 2,5

Step 1: Simplify the fractions: -1/1/9 can be interpreted as -1 / (1/9), which is -9. 1/3/5 can be interpreted as 1 / (3/5), which is 5/3.

Step 2: Evaluate the subtraction: 1/3/5 - 1=4 is unclear due to the formatting. If you meant 1 / (3/5) - 1, then: 1 / (3/5) - 1 = 5/3 - 1 = (5 - 3) / 3 = 2 / 3.

Step 3: Substitute the values into the expression: (-9) × (2/3) + 2.5

Step 4: Perform the multiplication: (-9) × (2/3) = -6.

Step 5: Add 2.5: -6 + 2.5 = -3.5.

So, the simplified value of the given expression is -3.5.
