Number names are a way of expressing the written form of numbers using letters. Learning number names will help you learn the basics of counting, addressing parcels, official documents, and so on. In this topic, we will learn number names from 400 to 500.
These are the words that we use to represent numbers, which makes it easier to read.
Take the number 450, it is written as ‘Four Hundred Fifty’.
Writing numbers in words not only helps us:
write legal documents
fill forms
but it also helps a student's spelling skills as well.
There are two different ways of naming numbers:
the Indian Numbering System
the International Numbering System
You need to understand how numbers are named using both numbering systems.
This will help you in:
communication
arithmetic calculations
Now let’s discuss the two numbering systems.
In the Indian Numbering System, digits are assigned place values starting from the right.
These place values include:
ones
tens
hundreds
thousands
ten thousands
lakhs
ten lakhs
crores
As the number increases, the place value continues to grow.
For example, in the number 486:
6 is in the ones place
8 is in the tens place
4 is in the hundreds place
Each digit has its value based on its position in the number.
Let’s take another example: 7,56,28,943
This number is written as:
Seven Crore Fifty-Six Lakhs Twenty-Eight Thousand Nine Hundred Forty-Three
The number gets placed as:
7 in the crores place
5 in the ten lakhs place
6 in the lakhs place
2 in the ten thousands place
8 in the thousands place
9 in the hundreds place
4 in the tens place
3 in the ones place
Just like the Indian Numbering System, the International Numbering System also uses place names, but they differ for larger numbers.
The place value starts from the right.
The place values are:
ones
tens
hundreds
thousands
hundred thousands
millions
ten millions
hundred millions
and so on
Let’s take the example: 843,956,729
This number is written as:
Eight Hundred Forty-Three Million Nine Hundred Fifty-Six Thousand Seven Hundred Twenty-Nine
The number gets placed as:
8 in the Hundred Million place
4 in the Ten Million place
3 in the Million place
9 in the Hundred Thousands place
5 in the Ten Thousands place
6 in the Thousands place
7 in the Hundreds place
2 in the Tens place
9 in the Ones place

Learning to write the numbers in words improves their skills in reading and writing.
While writing numbers from 400 to 500, there are certain rules to be followed. Below discussed are some rules to keep in mind while writing the names of numbers.
Rule 1: Always start naming with ‘Four Hundred’ for any number from 400 to 499. For example, 450 is written as Four Hundred Fifty.
Rule 2: For numbers starting with 500, use “Five Hundred.” For example, 501 is written as “Five Hundred One.”
