Question

The whole number that does not have a preceding whole number is .

Answer 1

$\underset{–}{\text{Predecessor of a Number}}:$
A predecessor is a number that precedes the given number or comes just before the given number.

Set of whole Numbers $=\text{{}0,1,2,3,...\text{}}$

From the above list of whole numbers, we can see that $‘‘0"$ is the smallest whole number; so there is no whole number that preceds $‘‘0"$. Therefore, $0$ has no preceding whole number.

$\underset{–}{\text{Notes}}:$

• $‘‘0"$ has a preceding number $-1,$ which does not belong to the list of whole numbers. Therefore, $‘‘0"$ does not have predecessor whole number.
• Predecessor of $0$ is $-1.$
