Rewrite the problem below as an equivalent addition expression and evaluate. -6 3/4- 2 1/2

- 6 3/4 + - 2 1/2 = -6 3/4 + - 2 2/4 = -8 5/4 = -9 1/4

-1-(-2)

To rewrite the problem as an equivalent addition expression, we can convert the mixed numbers into improper fractions and then add them.

First, let's convert -6 3/4 into an improper fraction:
-6 = -24/4 (since there are 4 quarters in one whole)
-6 3/4 = -24/4 + 3/4 = -21/4

Similarly, let's convert 2 1/2 into an improper fraction:
2 = 2/1
2 1/2 = 2/1 + 1/2 = 5/2

Now, we can rewrite the expression as an addition expression:
-21/4 - 5/2 = -21/4 + (-5/2)

To add these fractions, we need a common denominator. The smallest number that both 4 and 2 divide evenly into is 4, so we'll use 4 as the denominator.

Now, let's convert the fractions to have a denominator of 4:
-21/4 + (-5/2) = -21/4 + (-10/4)

Since we have the same denominator, we can add the numerators directly:
-21/4 + (-10/4) = (-21 - 10)/4 = -31/4

Therefore, the equivalent addition expression is -21/4 + (-5/2), which evaluates to -31/4.
