The number 105 is written as one hundred five. It is often used in contexts like counting items, representing scores, or marking pages. In this topic, we will be discussing 105 in words.
Writing numbers in words is essential when filling out official documents or checks. But how do we write a number like 105 in words? The answer lies in breaking the number into its place values.
Let’s look into how we represent 105 in its place values with the help of a place value chart. For 105, we split the number into hundreds, tens, and ones. 1 represents the hundreds place, 0 represents the tens place, and 5 represents the ones place.
Step 1: Begin with the leftmost digit, and assign each digit a place value as you move from left to right. For 105, we start from hundreds, tens, and then the ones place.
Step 2: Next, combine the values from each place and then read the values aloud. In 105, we can see that the number consists of 5 ‘ones’, 0 ‘tens’, and 1 ‘hundred’.
Starting from the leftmost value, read the number together from left to right, keeping in mind the place values. When we read it out loud, we read it as “one hundred five”.

Now that we have learned how to express the number 105 in words, let's explore more about the properties of the number.
The following points are a few common mistakes that children make. When writing numbers into words, it can get a little confusing:
Not placing digits in the correct place value order.
We must always ensure that the correct place value is used. A hyphen should be used to separate tens and ones in compound numbers from twenty-one through ninety-nine.
Example:
Incorrect: Forty three
Correct: Forty-three
Removing the zero when reading the words aloud
When reading numbers like 205 or 401, students may sometimes assume that 0 needs to be omitted, which is incorrect. This will affect the pronunciation of the number. Make sure zero is included as part of the number’s place value.
Example:
Incorrect: 205 (if we omit the zero, we would read it as twenty-five)
Correct: 205 should be read as two hundred five
Confusing similar sounding words with each other and making spelling mistakes.
There are a few numbers that have very similar sounds. We must make sure that we are clear with the pronunciation of the number. We must also make sure that when writing the numbers in words, we avoid spelling mistakes.
Example: Fifty being mistaken as fifteen. 500 being written as fifty thuosand.
Overuse of the word ‘and’
Overusing the word ‘and’ is a very common mistake that a lot of children make. This is common, especially in larger numbers.
Example:
Incorrect: 137 = One and hundred and thirty-seven
Correct: 137 = One hundred thirty-seven (notice the placement of ‘and’)
Reading or writing the numbers in the wrong order.
When children start learning about writing numbers in words, it is possible they may struggle with the sequence of numbers. So we need to stress the importance of the place values. Begin from the largest number to the smallest number.
Example:
Incorrect: 425 = Four hundred two five
Correct: 425 = Four hundred twenty-five.


Writing numbers in words is essential because it ensures clarity and prevents misunderstandings, especially when writing official documents like checks and contracts. It helps avoid small mistakes like skipping a zero and adding an extra layer of verification.
No, 1.05 is not the same as 105. 1.05 represents one and five-hundredths, which is a decimal. For formal documents or checks, we must write the entire number as one hundred five.
Follow the place value rules, use hyphens for compound numbers (21 to 99), and ensure that zeros are correctly represented in words.
The result is 579, and in words, we will write it as five hundred seventy-nine.
No, when we write the number in words, we will not use any commas.
For example, 105 would be written as one hundred five.
