Number Names 100 to 150

These are the words that we use to represent numbers, which makes it easier to read. Take the number 150, it is written as ‘One Hundred Fifty’. Writing numbers in words not only helps us write legal documents and fill forms, but it will also help a student's spelling skills as well. There are two different ways of naming numbers: 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.

Professor Greenline from BrightChamps

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 146, the digit 6 is in the ones place, 4 is in the tens place, and 1 is in the hundreds 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 one, tens, hundreds, thousands, hundred thousands, millions, ten millions, hundred millions, and so on. Let’s take the example of 743856269, 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 100 to 150

While writing numbers from 100 to 150, 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 ‘Hundred’ for any number from 100 to 199. For example, 150 is written as One Hundred Fifty. Rule 2: For numbers starting with 200, use “Two Hundred.” For example, 201 is written as “Two Hundred One.” Rule 3: Numbers after 100 follow a pattern. For example, 145 is written as One Hundred Forty-Five, 138 is written as One Hundred Thirty-Eight, and 122 is written as One Hundred Twenty-Two.

Tips and Tricks for Number Names 100 to 150

Always use a hyphen while writing numbers like 145 and 138. It should be written as One Hundred Forty-Five and One Hundred Thirty-Eight. Always keep writing the numbers with ‘Hundred’, as in One Hundred for 100 and Two Hundred for 200. Always focus on the tens place for numbers like 110, 120, 130, etc. After writing One Hundred, you just need to add the number, that's it. The mentioned numbers can be written as One Hundred Ten, One Hundred Twenty, and One Hundred Thirty.

Writing Two Hundred Zero instead of Two Hundred

Green Checkmark Icon Indicating Correct Solutions in This Math Topic

Students might get confused between Two Hundred Zero and Two Hundred for 200. The correct way to express 200 in words is Two Hundred. There’s no need to write zero after two hundred.

Mistake 3

Using ‘and’ while writing number names in American English

Green Checkmark Icon Indicating Correct Solutions in This Math Topic

We use ‘and’ while writing number names only in British English. For example, 110 is written as One Hundred and Ten. But in American English, we do not use ‘and’. The number 110 in American English is written as One Hundred Ten. Always make sure that students are aware of the difference.

Mistake 4

Mistake 5

Red Cross Icon Indicating Mistakes to Avoid in This Math Topic

Getting confused with the tens and ones place

Green Checkmark Icon Indicating Correct Solutions in This Math Topic

Students can get confused between numbers like 114 and 140. In 114, we have 4 in the ones place and 1 in the tens place. In 140, we have 0 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.
