Number Names 50 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 50 to 100.
Number Names 50 to 100
These are the words that we use to represent numbers, which makes it easier to read. Take the number 75, it is written as ‘Seventy-Five’.
Writing numbers in words not only helps us write legal documents and fill forms, but it also enhances a student's spelling skills.
There are two different ways of naming numbers: the Indian Numbering System and the International Numbering System. Understanding how numbers are named using both systems 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 86, the digit 6 is in the ones place, and 8 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 has its value based on its position in the number.
Let’s take an example of the number 9,56,28,743. The number is 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, which 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 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

Rules for Writing Numbers from 50 to 100
While writing numbers from 50 to 100, there are certain rules to be followed. Below are some rules to keep in mind while writing the names of numbers.
Rule 1: Always start naming with the tens digit for numbers from 50 to 99. For example, 75 is written as Seventy-Five.
Rule 2: For numbers ending in a zero, use the corresponding decade name. For example, 60 is written as Sixty.
Rule 3: Numbers after 50 follow a pattern. For example, 55 is written as Fifty-Five, 68 is written as Sixty-Eight, and 72 is written as Seventy-Two.
Tips and Tricks for Number Names 50 to 100
Always use a hyphen while writing numbers like 65 and 78. It should be written as Sixty-Five and Seventy-Eight. Always keep writing the numbers with their decade name, as in Fifty for 50 and One Hundred for 100.
Always focus on the tens place for numbers like 70, 80, 90, etc. After writing the decade name, you just need to add the number, that's it. The mentioned numbers can be written as Seventy, Eighty, and Ninety.
Common Mistakes and How to Avoid Them in Number Names 50 to 100
Students can make mistakes while learning number names. Let’s discuss a few mistakes a student can make while writing numbers from 50 to 100.
Mistake 1
Ignoring the Hyphen
Ignoring hyphens while writing numbers like 55 and 68 will consider the numbers as separate numbers. For example, 55 should be written as Fifty-Five and not Fifty Five.
Mistake 2
Writing Fifty Zero instead of Fifty
Students might get confused between Fifty Zero and Fifty for 50. The correct way to express 50 in words is Fifty. There’s no need to write zero after fifty.
Mistake 3
Using ‘and’ while writing number names in American English
We use ‘and’ while writing number names only in British English. For example, 70 is written as Seventy and Ten. But in American English, we do not use ‘and’. The number 70 in American English is written as Seventy. 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 Sixty-Seven as Sixty-Seven and not Sixty-Seaven.
Mistake 5
Getting confused with the tens and ones place
Students can get confused between numbers like 84 and 48. In 84, we have 4 in the ones place and 8 in the tens place. In 48, we have 8 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.
