How many tables in a row are needed to seat 105 students?

To determine how many tables are needed to seat 105 students, you first need to know how many students can sit at one table. For example, if each table seats 5 students, you would divide 105 by 5, resulting in 21 tables. If each table seats 6 students, you would need 18 tables (since 105 ÷ 6 = 17.5, rounding up to 18). The exact number of tables depends on their individual seating capacity.
