To determine the number of tables needed for 63 students, where there are 9 students seated at each table, you can follow these steps:
1. Divide the total number of students by the number of students at each table:
63 students ÷ 9 students per table = 7 tables
2. Therefore, the 63 students will be seated at 7 tables, with 9 students at each table.
Thus, there are 7 tables in the cafeteria where the students are seated, with 9 students at each table.
