Answer 2

To solve this expression, you can follow these steps:

1. Add the mixed numbers and the whole numbers separately.
2. Add the fractions separately.
3. Combine the results from steps 1 and 2.

Let's break it down:

-5 1/7 + 4 4/7 + 2 6/7 + (-12 - 7)

Step 1: Add the whole numbers: (-5) + 4 + 2 + (-12) + (-7) = -18

Step 2: Add the fractions: 1/7 + 4/7 + 6/7 = (1 + 4 + 6) / 7 = 11/7

Step 3: Combine the results from steps 1 and 2: -18 + 11/7

To add an integer to a fraction, you need to convert the integer to a fraction with the same denominator as the fraction. In this case, the denominator is 7:

-18 = -18/1

Now, you can add the fractions:

-18/1 + 11/7

To add these fractions, you need a common denominator, which is 7:

-18/1 * 7/7 + 11/7 = (-126/7) + (11/7)

Now, combine the fractions:

(-126 + 11) / 7 = -115/7

So, the final result is -115/7 or approximately -16.43 when expressed as a decimal.
