Answer 2

Let's solve the expression step by step:

1. Start with the innermost parentheses: (-6/10) equals -0.6.
2. Now, let's simplify the expression inside the parentheses: -19/25 + 2/5*(-0.6).
3. Calculate the multiplication: 2/5 * (-0.6) = -0.24.
4. Add the fractions: -19/25 - 0.24.

To add the fractions, you need a common denominator. In this case, the common denominator is 25:

(-19/25) - (24/100) = -19/25 - 24/100.

Now, let's find a common denominator for these fractions, which is 100:

(-19/25) = (-19/25) * (4/4) = (-76/100).

Now we can combine the fractions:

-76/100 - 24/100 = (-76 - 24)/100 = -100/100.

5. Now, simplify the remaining expression: (-100/100) * (8/10).

Here, the common factor is 100:

(-100/100) = (-100/100) * (1/1) = -1.

Now, calculate the multiplication:

-1 * 8/10 = -8/10.

Finally, we can simplify the fraction:

-8/10 = -4/5.

So, the result of the expression is -4/5.
