Answer 2

To add the two mixed numbers -6 5/6 and 3 5/8, we need to find a common denominator for the fractions.

The common denominator for 6 and 8 is 24.

Let's convert -6 5/6 and 3 5/8 into improper fractions:

-6 5/6 = - (6 * 6 + 5) / 6 = -41/6

3 5/8 = (3 * 8 + 5) / 8 = 29/8

Now we can add the fractions:

-41/6 + 29/8 = (-41 * 8 + 29 * 6) / (6 * 8) = (-328 + 174) / 48 = -154/48

To simplify the fraction, we can divide both the numerator and denominator by their greatest common divisor (GCD), which is 2:

-154/48 = (-154 ÷ 2) / (48 ÷ 2) = -77/24

Therefore, -6 5/6 + 3 5/8 is equal to -77/24.
