720 in Words

Before we learn more about 720 in words, let’s first understand a few basic rules. Always spell out numbers at the beginning of a sentence instead of writing the numeral. Another thing to remember is that when we write fractions, we must always use a hyphen (e.g., one-third). The same goes for all compound numbers like twenty-one or fifty-six. These are some basic rules one must always keep in mind when writing numbers in words.

How to write 720 in words?

Writing numbers in words is essential when filling official documents or checks. But how do we write a number like 720 in words? The answer lies in breaking the number into its place values.

 

Let’s look into how we represent 720 using a place value chart. So for 720, we split the number into hundreds, tens, and ones. 7 represents the hundreds in place, 2 represents the tens, and 0 represents the ones.

 

Step 1: Begin with the leftmost digit, and assign each digit a place value as you move from left to right. For 720, 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 720, we can see that the number consists of 0 ‘ones’, 2 ‘tens’, and 7 ‘hundreds’.

 

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 “seven hundred twenty”.

When reading numbers like 205 or 740, 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: 720 (if we omit the zero we would read it as seventy-two)

Correct: 720 should be read as seven hundred twenty
