Numbers in words

Using words to write numbers when writing something in English makes your work look classy and clean. More importantly, it makes your writing readable and eliminates the hurdle of reading numbers and words together. In handwriting, words are not just easy to write but also difficult to mistake for each other. Even though longer numbers that have a lot of zeros at the end are not as useful as writing shorter numbers, it is still an important skill to learn for a student.

English is the most common, if not the universal, language used in institutes specifically for teaching purposes. Therefore, a student must learn how to convert numbers to words in English when writing something that involves the use of numbers. If you struggle to write numbers in words on a daily basis, then you may need to hire a private tutor online to help you out. In the beginning, roman numerals were used to represent mathematical numbers when writing, such as 1-I, 2-II, 3-III, and 4-IV, etc. However, now the preferred way of representing numbers is to write them in English words.

Before you learn how to spell numbers in words or you start using them in English, you must get familiar with the basics. The precondition to learning how to spell numbers in words is to know how to count to ninety-nine.

Counting From One to Ninety Nine

Let’s start with one to nine because that is where it all starts. These few numbers make up the whole empire of maths. So, it is important to know how to write them in English before you learn something else. Once, your grasp on them is strong, learning the rest of the numbers feels like a piece of cake:

Now that you know how to write the first nine numbers in words, for example, how do you write 1 or 7 in words, it is time for you to move on to learning how to write numbers from ten to nineteen.

The key to learning and remembering this set of numbers is to keep one simple observation in mind that most of the numbers (except ten, eleven, and twelve) are just their basic spelling (from one to nine) with the word “teen” at their end.

For instance, “Fourteen” (14) is just a combination of four and ten and means “four plus ten” (4 + 10). So, if you are worried about how to write 13 or 12 in words, this small and simple hack has got your back.

Moreover, learning all the words from one to twenty will enable you to spell higher numbers in words. Another reason to learn every number from one to twenty in English is that every number word’s spelling (from one to twenty) is different from other numbers.

Once you know how to write from one to twenty in words, you can then proceed to learn about the rest of the numbers because your base is now strong. You can, at this point, learn to write any number you want in English whether it is how to write 50 in words, how to write 20 in words, or how to write 100.

The next step for you is to count from twenty to ninety in tens. Here is a demonstration of how to spell 20, 30, 40, 50, and so on all the way up to 100 in English.

One little hack for you here is that all these numbers, spelled in ten, end in the letters ‘ty’ except for 100.

Combining Words to Write More Numbers

You can write any number from one to hundred if your basics are strong. Let’s see an example of the number 56:

  • 56 is written with two numbers: 5 and 6
  • 6 is in the ones place and it is written as it is.
  • 5 is in the tens place and so it is written as fifty.
  • Write fifty and six together and add a hyphen between them.
  • So, 56 = fifty-six

Then you have the hundreds which are easy to write if you remember the basic numbers and their spellings. All you need to do is add the word ‘hundred’ after each number.

Numbers (Hundreds)Words
100One Hundred
200Two Hundred
300Three Hundred
400Four Hundred
500Five Hundred
600Six Hundred
700Seven Hundred
800Eight Hundred
900Nine Hundred

With the knowledge to write from one to hundred, any student can write any number higher than hundred. You just have to write the hundreds place, and then the rest of the numerical.

For example:

  • 130 will be one hundred thirty
  • 405 will be four hundred five
  • 666 will be six hundred sixty-six
  • 809 will be eight hundred eighty-nine 

Writing Long Numbers

Before you start writing longer numbers, it is important for you to understand place values. Based on where a digit is situated in a number it can mean something different, so you can’t mess up the place of the digit if you want to get the number right. Here are the first nine place values:


Numbers Place Values
1the ones place
10the tens place
100the hundreds place
1,000the thousands place
10,000the ten thousands place
100,000the hundred thousands place
1,000,000the millions place
10,000,000the ten millions place
100,000,000the hundred millions place

When writing higher numbers, you’ve to add commas. To add a comma, count three digits, starting from the right and add a comma. Repeat this to separate the number in groups of three.

For instance, 

1200567 will be 1,200,567. 

You can also add a period instead of a comma; if that is how the numbering system works where you live.

Writing Fractions in Words

If the denominator is the number 2, then such fractions are written as halves. So, 12is written as “one-half“, 23 is “two-halves“ and 192 is “nineteen-halves“, etc.

For the number 3 as denominator, the fractions are written as “third-thirds“. For 4, the fractions are “fourth/fourths“. And for 27, the fractions are “twenty-sevenths“, etc.

Writing Mixed Numbers in Words

Mixed numbers are numbers that have a whole number and a fraction together. Let’s look at an example to see how you can write a mixed number:

Consider 745 as the sample number. When writing it in words, it will be “seven and four-fifths“.
