Answer 3

To simplify the expression, let's convert all the mixed numbers into improper fractions first:

-5 2/3 = (-5 * 3 + 2) / 3 = -17/3 4 5/6 = (4 * 6 + 5) / 6 = 29/6 -(-7 1/2) = 7 1/2 = (7 * 2 + 1) / 2 = 15/2

Now, we can substitute these values back into the expression:

-17/3 - 29/6 - 15/2

To add or subtract fractions, we need a common denominator. The least common multiple of 3, 6, and 2 is 6. Let's convert all the fractions to have a denominator of 6:

-17/3 = -34/6 29/6 (already in the desired form) 15/2 = 45/6

Now, we can subtract the fractions:

-34/6 - 29/6 - 45/6

To subtract the fractions, we subtract the numerators while keeping the denominator the same:

= (-34 - 29 - 45) / 6 = (-108) / 6 = -18

Therefore, the expression -5 2/3 - 4 5/6 - (-7 1/2) equals -18.
