Number Names 91 to 100
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 91 to 100.
Number Names 91 to 100
These are the words that we use to represent numbers, which makes it easier to read. Take the number 95, it is written as ‘Ninety-Five’.
Writing numbers in words not only helps us write legal documents and fill forms, but it also helps a student's spelling skills as well.
There are two different ways of naming numbers. They are the Indian Numbering System and the International Numbering System.
You need to understand how numbers are named using both numbering systems. This will help you in communication as well as in arithmetic calculations.
Now let’s discuss the two numbering systems.
Indian Numbering System
In the Indian Numbering System, digits are assigned place values starting from the right. These place values include ones, tens, hundreds, and thousands, and continue to grow as the number increases.
For example, in the number 96, the digit 6 is in the ones place, and 9 is in the tens place.
Starting from the right, the order goes from ones to tens, hundreds, thousands, ten thousands, lakhs, ten lakhs, and crores.
Each digit will have its value based on its position in the number.
Let’s take an example of the number 9,56,28,743:
The number gets written as Nine Crore Fifty-Six Lakhs Twenty-Eight Thousand Seven Hundred Forty-Three.
The number gets placed as:
-
9 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
-
7 in the hundreds place
-
4 in the tens place
-
3 in the ones place
International Numbering System
Just like the Indian Numbering System, the International Numbering System also uses names, and they differ for bigger 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 of 743,856,269:
The number is written as Seven Hundred Forty-Three Million Eight Hundred Fifty-Six Thousand Two Hundred Sixty-Nine.
The number gets placed as:
-
7 in the Hundred Million place
-
4 in the Ten Million place
-
3 in the Million place
-
8 in the Hundred Thousands place
-
5 in the Ten Thousands place
-
6 in the Thousands place
-
2 in the Hundreds place
-
6 in the Tens place
-
9 in the Ones place

Common Mistakes and How to Avoid Them in Number Names 91 to 100
Students can make mistakes while learning number names. Let’s discuss a few mistakes a student can make while writing numbers from 91 to 100.
Mistake 1
Ignoring the Hyphen
Ignoring hyphens while writing numbers like 95 and 98 will consider the number as separate numbers. For example, 95 should be written as Ninety-Five and not Ninety Five.
Mistake 2
Writing One Hundred Zero instead of One Hundred
Students might get confused between One Hundred Zero and One Hundred for 100. The correct way to express 100 in words is One Hundred. There’s no need to write zero after one hundred.
Mistake 3
Using ‘and’ while writing number names in American English
We use ‘and’ while writing number names only in British English. For example, 91 is written as Ninety-One. But in American English, we do not use ‘and’. The number 91 in American English is written as Ninety-One. Always make sure that students are aware of the difference.
Mistake 4
Incorrect spelling
While writing the number names, be sure that you have written it correctly. For example, a child can write Ninety-Five and Ninety-Fif.
Mistake 5
Getting confused with the tens and ones place
Students can get confused between numbers like 94 and 49. In 94, we have 4 in the ones place and 9 in the tens place. In 49, we have 9 in the ones place and 4 in the tens place. To avoid these, students need to learn how to pronounce the numbers correctly. Once they learn to pronounce the numbers, they can write the number names correctly.
