To add or subtract fractions, we need to have a common denominator.
For the given expression, the common denominator is 12, as it is divisible by both 3 and 4.
Now we convert 7 2/3 into an improper fraction:
7 2/3 = (7 * 3 + 2) / 3 = 23/3
Also, we convert -5 1/4 into an improper fraction:
-5 1/4 = (-5 * 4 + 1) / 4 = -21/4
Now, the given expression becomes:
23/3 + (-21/4)
To add or subtract fractions, the denominators must be the same.
The least common multiple of 3 and 4 is 12, and we need to modify both fractions to have a denominator of 12:
(23/3) * (4/4) = 92/12
(-21/4) * (3/3) = -63/12
Now the expression becomes:
92/12 + (-63/12)
Combine the numerators:
92 - 63 = 29
The final expression is:
29/12
