It is easy to avoid dividing by zero with a numerical fraction because you can:
ASee the denominator
BIgnore the numerator
CRound the fraction
DCancel the fraction
Answer & Solution
Correct answer: A. See the denominator
1. Numbers are more transparent than variables.
2. Division by zero is undefined in every case.
3. When we work with a numerical fraction, it is easy to avoid dividing by zero.
4. That is because we can see the number in the denominator.
