Place value is used to read and write multi-digit whole numbers.
The number has a 3 in the ten thousands place, which is written as
thirty thousand.
The number has a 7 in the thousands place, which is written as
seven thousand.
The number has a 4 in the hundreds place, which is written as
four hundred.
The number has a 1 in the tens place and a 9 in the ones place, which is written as nineteen.
In the number, there is a comma between the thousands and hundreds places.
So, put a comma between "thirty-seven thousand" and "four hundred."
The number written in words is thirty-seven thousand, four hundred nineteen.
First, identify which digit is in each place.
| thousands | 2 |
| hundreds | 9 |
| tens | 4 |
| ones | 6 |
Then, write the digits as a number.
Put a comma every three digits, starting from the ones place and moving left.
