Given that,

Uma has invited 7 friends to the dinner party.

So, there are 7! Possibilities i.e, 5040 arrangements.

However, because there are five seats at the table, each UNIQUE arrangement is repeated five times.

Therefore, the possible seating arrangements are \mathrm{ \frac{5040}{7}=720\ ways.}
