**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.
