To simplify the expression 7 2/3 + -5 1/4, we first need to convert the mixed numbers to improper fractions.
7 2/3 = (7 * 3 + 2)/3 = 23/3
-5 1/4 = (-5 * 4 + 1)/4 = -19/4
Now, we can add the fractions:
23/3 + (-19/4)
To add fractions with different denominators, we need to find a common denominator. In this case, the common denominator is 3 * 4 = 12.
Multiplying the numerators and denominators by the appropriate factors, we get:
(23 * 4 + (-19 * 3)) / 12
= (92 - 57) / 12
= 35/12
Therefore, the simplified expression is 35/12.
