Question

What is the predecessor of the smallest $5-$digit number?

Answer 1

Determine the predecessor of the smallest $5$-digit number.

Any number's immediate antecedent is the value that comes before the original number.

Therefore, the predecessor of any number is $1$ less than the given number.

It is known that the smallest $5-$-digit number is $10,000$.

So, the predecessor of $10,000$ is $10,000-1=9999$.

Hence, the predecessor of the smallest $5$-digit number $10,000$ is $9999$.
