Answer:
Sum. If the problem asks to add the two fractions, the result is:
[tex]\frac{29}{24}[/tex]
Step-by-step explanation:
If you mean to simply state whether this is a sum or a difference, it's a sum.
This is because of the + sign present between the two fractions which indicates it's an addition.
If it was a - it would indicate it was a subtraction problem (or difference)
In order to solve this, we will have to get a common denominator on both fractions. In this case, to do this, we can multiply each denominator to the other fraction, such that:
[tex]3(\frac{7}{8}) + 8(\frac{1}{3})\\\\\frac{21}{24} + \frac{8}{24}\\\\\frac{21 + 8}{24}\\\\\frac{29}{24}\\[/tex]
This can't be simplified further, but can be represented in decimal form as 1.20833.
Good luck!
