If eudora needs a total of 12 pieces of the shorter ribbon, how many more pieces of the ribbon does she need

Huh?

To determine how many more pieces of the ribbon Eudora needs, we need to know the number of pieces she already has. Please provide that information.

To determine how many more pieces of the ribbon Eudora needs, we need to know how many pieces of the shorter ribbon she already has. Once we have that information, we can subtract the number of pieces she already has from the total number of pieces she needs.

Since we don't have the information about how many pieces of the shorter ribbon Eudora already has, we cannot give an exact answer. If you can provide the number of shorter ribbons Eudora already has, I would be happy to help you calculate how many more pieces she needs.
