Answer 2

To simplify the expression:

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

First, let's simplify the mixed numbers:

-1 2/5 = -7/5 -3,6 = -18/5 -2 5/6 = -17/6 -2/3

Now, let's rewrite the expression:

(-7/5 + (-18/5)) + (-17/6 + (-2/3))

Next, add the fractions within each set of parentheses:

-7/5 + (-18/5) = -7/5 - 18/5 = (-7 - 18)/5 = -25/5 = -5

-17/6 + (-2/3) = -17/6 - 4/6 = (-17 - 4)/6 = -21/6 = -7/2

Now, you have:

-5 + (-7/2)

To add these two fractions, find a common denominator, which is 2 in this case:

-5 can be written as -10/2

So, the expression becomes:

(-10/2) + (-7/2)

Now, add the fractions:

(-10/2) + (-7/2) = (-10 - 7)/2 = -17/2

So, the simplified expression is -17/2.
