Answer 2

Let's break down the given expression step by step:

1. Start with the first part: -8 5/12 - 13. -8 5/12 is a mixed number, which can be converted to an improper fraction as follows: -8 5/12 = - (8 * 12 + 5) / 12 = -101 / 12

   So, the first part becomes: -101 / 12 - 13.

2. Move on to the second part: -3 5/6 - 2 1/4. -3 5/6 is a mixed number, which can be converted to an improper fraction as follows: -3 5/6 = - (3 * 6 + 5) / 6 = -23 / 6

   -2 1/4 is also a mixed number, which can be converted to an improper fraction as follows: -2 1/4 = - (2 * 4 + 1) / 4 = -9 / 4

   So, the second part becomes: -23 / 6 - (-9 / 4).

3. Distribute the negative sign in the second part: -23 / 6 + 9 / 4.

4. Find a common denominator for the fractions, which is 12 (the least common multiple of 6 and 4).

   -23 / 6 = - (23 * 2) / (6 * 2) = -46 / 12 9 / 4 = (9 * 3) / (4 * 3) = 27 / 12

5. Now, the second part becomes: -46 / 12 + 27 / 12.

6. Add the fractions together: -46 / 12 + 27 / 12 = -19 / 12.

7. Combine the results of the first and second parts: -101 / 12 - 13 + (-19 / 12).

8. Find a common denominator for the fractions in the first part and the combined result.

   -101 / 12 = -101 / 12 -13 = -13 -19 / 12 = -19 / 12

9. Add the fractions together: -101 / 12 - 13 - 19 / 12 = - (101 + 19) / 12 - 13 = -120 / 12 - 13 = -10 - 13 = -23.

So, the final result of the expression is -23.
