Answer 2

To simplify the expression, let's start by simplifying the terms inside the parentheses first:

-1 1/3 can be rewritten as -4/3. -1/6 remains the same.

Now, we can substitute these values back into the original expression:

2,5 - (-1 1/3 + (-1/6))

= 2,5 - (-4/3 + (-1/6))

Next, let's simplify the expression inside the second set of parentheses:

-4/3 + (-1/6) can be simplified by finding a common denominator:

-4/3 + (-1/6) = -8/6 + (-1/6) = -9/6

Substituting this back into the expression:

2,5 - (-9/6)

Now, we can simplify further by multiplying the numerator and denominator of -9/6 by 2 to get a common denominator with 2,5:

2,5 - (-9/6) = 2,5 - (-18/12)

Now, we have:

2,5 - (-18/12)

To subtract a negative number, we can rewrite it as addition:

2,5 + 18/12

Next, let's simplify the fraction by finding a common denominator with 12:

2,5 + 18/12 = 2,5 + (18/12) * (1/1) = 2,5 + (18/12) = 2,5 + (3/2)

Now, we need to find a common denominator between 2 and 3:

2,5 + (3/2) = (5/2) + (3/2)

Adding the numerators together:

(5/2) + (3/2) = 8/2 = 4

Therefore, the simplified expression is 4.
