There are 103 students eating lunch in the cafeteria. each table seats 4 students. all the tables are full except for 1 table. how many students are sitting at the table that is not full?

4*25= 100. There are 26 tables. At each of the 25 tables 4 people are sitting. Which means 100 people are sitting in complete tables of 4 people. That means that at the 26th table 3 people are sitting. 103-100= 3. Hope that helps. :) 

You're looking for the reminder, or "left overs", of a division problem. 103/4=25 r3 or 25 full tables and people left over, so your answer is 3 students
