How to write numbers in word form
We can write all types of numbers, such as integers, fractions, and decimal numbers, in word form.
Integers
Recall that integers are the set of all positive and negative whole numbers including 0. For the smaller numbers, like 1-20 we just need to remember what the numbers are called.
1-20 | |
---|---|
1 — one | 11 — eleven |
2 — two | 12 — twelve |
3 — three | 13 — thirteen |
4 — four | 14 — fourteen |
5 — five | 15 — fifteen |
6 — six | 16 — sixteen |
7 — seven | 17 — seventeen |
8 — eight | 18 — eighteen |
9 — nine | 19 — nineteen |
10 — ten | 20 — twenty |
Note that any negative number is written in word form in the same way except that the word «negative» is written in front. Once we know how to write each of the above numbers in word form, the next step is to remember what every 10 numbers is referred to:
10 — ten |
---|
20 — twenty |
30 — thirty |
40 — forty |
50 — fifty |
60 — sixty |
70 — seventy |
80 — eighty |
90 — ninety |
Numbers that include both tens and ones are hyphenated. For example, 21 is written as twenty-one, 39 is written as thirty-nine, and so on.
Writing larger numbers in word form requires an understanding of place value and periods. Below is a figure showing the place values and periods through the billions.
The numbers described above fall within the ones period and involve ones, tens, and hundreds. The next period is the thousands, which also includes ones (thousand), tens (ten thousand), and hundreds (hundred thousands). This pattern continues for all the larger numbers (the smaller ones as well, if there are decimal places). To write a given number in word form, identify the largest place value, write each number as we would in the ones place based on hundreds, tens, and ones, then write which period the digits fit into, whether it be millions, thousands, etc., but excluding the ones. Repeat this process from left to right.
Example
Use the place value chart to write the following number in word form.
There are 4 periods in the above number: billions, millions, thousands, and ones. We can separate each period with commas, as we would with numerals. Write out the word form of the three digits in each period, then add the respective period name after each, except for the ones period. Attempt this before reading the solution below.
The word form of the above number is:
Two hundred forty-nine billion, five hundred fifty-one million, six hundred seventy-two thousand, four hundred eighty-six.
Decimal numbers
Decimal numbers are written in word form in a similar way as integers. One key difference is the addition of the decimal point, which is written as «and.» The numbers after the decimal point are written in the same way as any integer, except that the last digit in the number is hyphenated, and the place value of the digit is written after the hyphen. For example, the decimal number 123.123 is written in word form as «One hundred twenty-three and one hundred twenty-three-thousandths.»
The table below shows the name of each place based on the place value of the number 1:
Decimal | Place value |
---|---|
0.1 | tenths |
0.01 | hundredths |
0.001 | thousandths |
0.0001 | ten-thousandths |
0.00001 | hundred-thousandths |
0.000001 | millionths |
0.0000001 | ten-millionth |
0.00000001 | hundred-millionth |
0.000000001 | billionth |
Thus, to write any decimal number:
- Write the word form of the number to the left of the decimal point first, then the word form of the number to the right.
- Hyphenate the last word in the word form of the number to the right of the decimal point.
- Write the place value of the last digit after the hyphen.
Fractions
The rules for writing fractions in word form are not as consistent as those for writing a decimal number, so instead of set rules, below are a few examples of the word forms of various fractions, as well as some general rules that apply to many fractions.
Generally, aside from exceptions, such as the word form of ½ being «one half» not «one second,» the rules below can be used to write the word form of most fractions.
- Write the word form of the integer in the numerator.
- Write the denominator in its ordinal number form.
How do you write numbers in word form?

Decimals represent parts of whole numbers. To write decimals in word form, first make sure you learn place value and know the names of the places after the decimal point. Once you understand place value, you can write out the decimal.

Recall the ones, tens, and hundreds places. It can help to quickly go over the place value for whole numbers before thinking about place value for decimals. Every digit in the ones place represents one whole (i.e. 7 is the same as 7 ones). In the tens place, every digit represents ten wholes. For example, the number 30 is 3 tens. Every digit in the hundreds place represents one hundred wholes. So the number 837 is 8 hundreds, 3 tens, and 7 ones, which we call eight hundred thirty-seven.[1]
- Every time you move right in the number, the place value gets 10 times smaller.
-
2
Understand what a decimal point is. The decimal point separates the whole number from the decimal value. Numbers after the decimal point represent fractions, or parts of numbers.[2]
- Just like on the other side of the decimal point, the numbers get 10 times smaller every time you move right a place value. For instance, 0.1 is ten times bigger than 0.01, which in turn is ten times bigger than 0.001, just like how 10 is ten times bigger than 1.

Note that the tenths place is the first place after the decimal. The number 0.1 represents one tenth. Each time you move to the right, the number is 1/10 as big as the previous number, which is why 0.1 is ten times smaller than 1.[3]
- In the US, a dime is one-tenth of a dollar, or $0.10. Coins can be a helpful way to think about decimals.
-
4
Recognize the hundredths place as the second place after the decimal. 0.01 is one hundredth. A hundredth is 1/100 of a whole, so it would take a 100 hundredths to make 1.[4]
- A penny is one hundredth of a dollar, or $0.01.
-
5
Learn that the thousandths place is the third place after the decimal. The number 0.001 is one thousandth. One thousandth is 1/1000 of a whole. Imagine splitting a whole into 1,000 pieces and taking one of those pieces—that would be one thousandth. If you took four pieces, 0.004, that’s four thousandths.[5]
- When you’re just learning decimals, you might stick with just the tenths and hundredths place. The thousandths place will be useful later on, though.
-
6
Ignore zeros if they are at the end of the decimal. For example, 0.5, 0.50, and 0.500 represent the same value, so you can just ignore the ending zeros when writing the decimal in words. Don’t ignore zeros in the middle of the decimal though. For example, 0.03 and 0.3 are very different numbers.[6]
- If you’re confused about why you can ignore zeros at the end, think of the decimals as fractions. 0.5 is 5/10, 0.50 is 50/100 and 0.500 is 500/1000. All of those are the same fraction, ½.

Write out the whole number normally. For the part of the number before the decimal point, write it out as you usually would. You have to remember place value when you are writing whole numbers.[7]
- For example, 3,450.02 would be three thousand four hundred fifty and two hundredths.
-
2
Put down “and” for the decimal point if it comes after a whole number. For example, if the number is 40.05, write “forty and five hundredths.” Most teachers prefer that you write “and” instead of “point.”[8]
- The word “and” helps people know that you are switching from whole numbers to parts of numbers.
-
3
Note that you don’t write «and» if the number is less than one. When writing decimals that have a zero in the ones place, like 0.2 or 0.017, don’t write “point,” “and” or anything else. Just start writing the number. For example, write 0.9 as nine tenths, whereas 1.9 is one and nine tenths.[9]
- You don’t need the word «and» to mark the transition between whole numbers and decimal numbers in numbers less than 1 because there is no transition.
-
4
Write the numbers after the decimal point as a whole number. For example, write .052 as “fifty-two thousandths.” Similarly, 0.52 is «fifty-two hundredths.» No matter how many zeros there are before other numbers start, you still write it the way you would write a whole number.[10]
- Don’t write the word “and” other than to represent the decimal point. For instance, write .103 as one hundred three thousandths, not one hundred and three thousandths.
-
5
End with the place value of the last digit. For example, the number 0.003 is three thousandths, because 3 is in the thousandths place. Alternatively, 0.523 is five hundred twenty-three thousandths because it also ends with the thousandths place. The number 0.92 is ninety-two hundredths.[11]
- Remember to ignore zeros at the end of decimals. Write 0.890 as eighty-nine hundredths, not eight hundred ninety thousandths.
-
6
Hyphenate if the last 2 digits are expressed in 2 words. For example, write 0.32 as thirty-two hundredths with a dash between thirty and two because 32 is written in 2 words. On the other hand, write 0.12 as twelve hundredths because 12 can be written as just 1 word.[12]

One way to help understand place value is by writing numbers in standard form, word form, and expanded form. For example, 9 in 129 has a different value than the 9 in 192. Knowing how to represent numbers in these three different ways will help build place value concepts.
What are these three forms of writing numbers?
Standard form is the usual way of writing numbers. One example is 756. This is how we see numbers everyday in the grocery, on our phones, computers, etc.
Expanded form is breaking down the numbers in such a way that you see the value of each number. So, the expanded form of 756 is 700 + 50 + 6.
Word form is when you write a number the way that you read it. When you see the number 756, you write it as “seven hundred fifty-six”.
How do you write numbers in standard form to word form?
When writing numbers from standard form to word form, having a place value chart will be very helpful. A place value chart shows how each digit in a number is related. It helps you read and separate the values into groups of three especially with big numbers.
Just look at this number 612,321,589. This number is read as “six hundred twelve million, three hundred twenty-one thousand, five hundred eighty-nine”. Notice that for each group of three, there is a comma or sometimes a space. These commas or spaces are not just for ease of reading. Commas also indicate the period or the group of digits in your number.
How do you write numbers in standard form to expanded form?
When writing numbers in expanded form, you will also find a place value chart helpful. Place value chart not just shows how the numbers are grouped, but also shows that each digit in a number increases by a power of ten from right to left. This will help decompose a number so that your students will know that having a 9 in the tens place has a different value than having a 9 in the hundreds place.
Here’s a place value chart showing the value of a number.
When the number 721,345,698 is placed in a place value chart, you will see the following:
- 7 is in the hundred millions place and has a value of 700,000,000
- 2 is in the ten millions place and has a value of 20,000,000
- 1 is in the millions place and has a value of 1,000,000
- 3 is in the hundred thousands place and has a value of 300,000
- 4 is the ten thousands place and has a value of 40,000
- 5 is in the thousands place and has a value of 5,000
- 6 is in the hundreds place and has a value of 600
- 9 is in the tens place and has a value of 90
- 8 is in the ones place and has a value of 8
When you put them all together, you will have a number written in expanded form. So 721,345,698 written in expanded form is 700,000,000 + 20,000,000 + 1,000,000 + 300,000 + 40,000 + 5,000 + 600 + 90 + 8.
To start practicing converting numbers into their different forms, you can try our Match the Numbers worksheet. This activity asks the students to match the standard, expanded, and word forms of each number. This is a cut-and-paste activity but is easily convertible to just a pen-and-paper activity. An answer key is included on the second page.

Using base-ten blocks is another good tool to help decompose a number in expanded form. You can start with our Place Value with Base-ten Blocks activity.
