Question 72

Question. 72

Any non-zero whole number divided by itself gives the quotient 1.

Answer:

true

Detailed Answer with Explanation:

  1. Pick any whole number and call it a. We must have \(a \neq 0\).
  2. Dividing a number by itself means: “How many groups of size \(a\) are there in \(a\)?”
  3. In \(a\) things, there is exactly one full group of size \(a\).
  4. So, \(a \div a\) gives \(1\).
  5. Therefore, for any non-zero whole number, \(a \div a = 1\).
  6. Reminder: when \(a = 0\), expressions like \(0 \div 0\) are not allowed (undefined). We only use \(a \neq 0\).
