The straightforward answer to how to write 78,500 in words or spell 78,500 is Seventy-eight thousand five hundred.
However, if you are interested in learning how we got to this answer so that you can use the method to determine how to express other numbers in words as well, we will have to use what is called a place value chart.
But before we even do that, let me first explain what is a place value chart.
A chart that depicts the place value of numbers is called a place value chart. To explain using an example, here is what a place value chart looks like:
| Hundred Million | Ten Million | Millions | Hundred Thousand | Ten Thousand | Thousands | Hundreds | Tens | Ones |
| 100,000,000 | 10,000,000 | 1,000,000 | 100,000 | 10,000 | 1000 | 100 | 10 | 0 |
Every digit in a number has a place value, which can be used to depict its position in the place value table.
If we were to depict the number 78,500 in a place value table, here is what it would look like
| Hundred Million | Ten Million | Millions | Hundred Thousand | Ten Thousand | Thousands | Hundreds | Tens | Ones |
| 0 | 0 | 0 | 0 | 7 | 8 | 5 | 0 | 0 |
Once we put it in the place value table, it becomes easy to determine how to write 78,500 in words — Seventy-eight thousand five hundred.
This same methodology can be used to determine how to represent other numbers in words as well.
