The inverse operation of multiplying by 5 is dividing by 5.
For example, if you have a number \( x \) and you multiply it by 5, you can reverse that operation by dividing the result by 5:
- Start with \( x \).
- Multiply by 5: \( 5x \).
- To find the original number \( x \) again, divide by 5: \( \frac{5x}{5} = x \).
So, in summary, the inverse of multiplying by 5 is dividing by 5.
