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 20 to 30.
These are the words that we use to represent numbers, which makes it easier to read. Take the number 25, it is written as ‘Twenty-Five’. Writing numbers in words not only helps us write legal documents and fill forms, but it also improves a student's spelling skills. There are two different ways of naming numbers. They are the Indian Numbering System and the International Numbering System. Understanding both numbering systems will assist in communication and 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, and thousands, and continue to grow as the number increases. For example, in the number 28, the digit 8 is in the ones place, and 2 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 29,743. The number gets written as Twenty-Nine Thousand Seven Hundred Forty-Three. The number gets placed as: 2 in the ten thousands place 9 in the thousands place 7 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 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 2,743,856. The number is written as Two Million Seven Hundred Forty-Three Thousand Eight Hundred Fifty-Six. The number gets placed as: 2 in the Million place 7 in the Hundred Thousands place 4 in the Ten Thousands place 3 in the Thousands place 8 in the Hundreds place 5 in the Tens place 6 in the Ones place
Learning the names of the numbers from 20 to 30 using a chart will make it easy for the students to write the numbers in words. List of Numbers in Words 20 to 30 The list given below shows how numbers from 20 to 30 are written using letters. Learning to write the numbers in words improves skills in reading and writing.
While writing numbers from 20 to 30, 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 place. For example, 25 is written as Twenty-Five. Rule 2: Numbers after 20 follow a pattern. For example, 22 is written as Twenty-Two, 27 is written as Twenty-Seven, and 29 is written as Twenty-Nine.
Always use a hyphen while writing numbers like 25 and 28. It should be written as Twenty-Five and Twenty-Eight. Focus on the ones place for numbers like 21, 22, 23, etc. After writing Twenty, you just need to add the number, that's it. The mentioned numbers can be written as Twenty-One, Twenty-Two, and Twenty-Three.
