Question

What is the Predecessor of $$100,000,000$$ is ?

Answer 1

Hint: Here in this question, we need to find the predecessor of 1 billion or $$100,000,000$$. As we know, in mathematics, the predecessor means the number that comes before the given number. So, the predecessor of a number is obtained by subtracting 1 from the given number. So, to find the predecessor of $$100,000,000$$, we will subtract 1 from it.

Complete step-by-step solution:
In mathematics, the term successor or predecessor suggests that numbers come directly after or before the particular number respectively. Just directly means by adding 1 to the particular or given whole number which gets a successor of it. Whereas to find the predecessor of a particular or given whole number we will subtract one from the given number.
Consider the given question:
We need to find the predecessor of $$100,000,000$$.
We have to subtract 1 from $$100,000,000$$ to get a predecessor of it.
$$ \Rightarrow \,\,100,000,000 - 1$$
On subtracting, we get
$$\therefore \,\,\,\,99,999,999$$
$$99,999,999$$ is a number that comes before the number $$100,000,000$$.
Therefore, the predecessor of $$100,000,000$$ is $$99,999,999$$.

Note: We have found the predecessor of $$100,000,000$$. Now, let us see what was the successor of it.
$$ \Rightarrow \,\,100,000,000 + 1 = 100,000,001$$
Successor of $$100,000,000$$ is $$100,000,001$$.
Remember, both the successor and predecessor are applied only to the whole numbers which are not applied to the fractions, decimals, or negative numbers.
Every whole number has its predecessor except zero.
