The place value of a digit in a number is determined by its position or location within the number. Each place value is ten times greater than the one to its right. In order to determine the place value of 7, we need to consider the commas in the number.

**Understanding Commas**

Commas are used to separate groups of three digits in large numbers. They help us read and understand the number easily by breaking it down into smaller parts. Let's take an example to understand how commas work.

The number 1,234,567 has three commas. We can read this number as "one million, two hundred thirty-four thousand, five hundred sixty-seven." The commas separate the number into three main parts: millions, thousands, and units.

**Determining the Place Value of 7**

To determine the place value of 7, we need to identify its position in relation to the commas in the number. Let's consider the number 1,234,567 again.

- The digit 7 is to the right of the last comma, which separates the thousands and units places.
