Question

Write the predecessor of the following:
(a) 8,48,300
(b) 1,00,000
(c) 1,73,970
(d) 57000

Answer 1

Hint: In this question, we have to find the predecessor of the following numbers. Predecessor actually means one number before that given number. Successor means the number which is next to the given number. We should also know what are natural numbers and whole numbers.

Complete step by step solution:
Let’s discuss the question now.
As we all know what numbers are! They are used to measure, to count the things, to label the objects etc. They are expressed using digits 0, 1, 2, 3, 4, 5, 6, 7, 8 and 9. Natural numbers are those which start from 1. And whole numbers are those which start from 0. Whole numbers contain natural numbers as well. Numbers can be expressed as positive and negative. Numbers which are positive are expressed without ‘-‘ sign. And numbers which are negative are expressed with the ‘-‘ sign before that number.
Predecessor of a number is the number which comes before that number. The successor is that number which comes after that number.
In question we have to find the predecessor of given numbers. So the predecessors are:
(a) 8,48,300 = 8,48,299
(b) 1,00,000 = 99,999
(c) 1,73,970 = 1,73,969
(d) 57000 = 56999
So this is the final answer.

Note: We have an alternative method also to find the predecessor of a number. Let’s find the predecessor of each number given in question using this method. First number given is: 8,48,300. If we subtract 1 from this number, we will be the predecessor of this number. Let’s see how.
$\begin{align}
  & 848300 \\
 & -\text{ }1 \\
 & \overline{848299} \\
\end{align}$
See we get the same answer that we got above. Similarly find the next one.
$\begin{align}
  & 100000 \\
 & -\text{ 1} \\
 & \overline{\text{ }99999} \\
\end{align}$
Next one is:
$\begin{align}
  & 137970 \\
 & -\text{ 1} \\
 & \overline{137969} \\
\end{align}$
Last one is:
$\begin{align}
  & 57000 \\
 & -\text{ 1} \\
 & \overline{56999} \\
\end{align}$
