Answer 2

It seems like you're trying to perform a series of mathematical calculations involving decimals and fractions. Let's break down the expression step by step:

1. -(6.77 - 5/4/9):

   • First, let's convert the fraction to a decimal: 5/4/9 = 5/4 * 1/9 = 5/36 ≈ 0.1389.
   • Now subtract it from 6.77: 6.77 - 0.1389 ≈ 6.6311.
   • Applying the negative sign: -(6.6311) = -6.6311.

2. -(0.23 - 3/5/9):

   • Convert the fraction to a decimal: 3/5/9 = 3/5 * 1/9 = 3/45 = 1/15 ≈ 0.0667.
   • Subtract it from 0.23: 0.23 - 0.0667 ≈ 0.1633.
   • Applying the negative sign: -(0.1633) = -0.1633.

3. -15.26 - (-34.35):

   • Subtracting a negative is the same as adding a positive: -15.26 + 34.35 = 19.09.

4. 24.62 - (-4.73):

   • Similarly, subtracting a negative is the same as adding a positive: 24.62 + 4.73 = 29.35.

5. -81.77:

   • This number remains as it is: -81.77.

Now let's put it all together:

-6.6311 - (-0.1633) + 19.09 + 29.35 - 81.77 ≈ -39.0844.

So, the result of the given expression is approximately -39.0844.
