Questions & Step-by-Step Solutions

In a classroom, the teacher wants to arrange chairs in rows such that each row has the same number of chairs. If there are 36 chairs, which of the following is NOT a possible number of chairs per row?
  • Step 1: Understand that we need to find numbers that can evenly divide 36. These numbers are called factors.
  • Step 2: List the factors of 36. The factors are: 1, 2, 3, 4, 6, 9, 12, 18, and 36.
  • Step 3: Check if the number 5 is in the list of factors. It is not.
  • Step 4: Conclude that since 5 is not a factor of 36, it cannot be a possible number of chairs per row.
  • Factors – Understanding factors involves identifying numbers that can divide another number without leaving a remainder.
  • Divisibility – Divisibility rules help determine whether one number can be divided by another without a remainder.
