Eight students share 5 blocks of modeling clay equally. What fraction of one block of modeling clay does each student get?

5/8

To find the fraction of one block of modeling clay that each student gets, you need to divide the total number of blocks of clay by the number of students.

In this case, there are 8 students sharing 5 blocks of clay equally. To find the fraction, you divide 5 by 8:

5/8

So, each student gets 5/8 or five-eighths of one block of modeling clay.
