Place Value Chart Analysis: Reading the Number 3,151,507

To determine the number represented by the place value chart, we will follow these steps:

• Step 1: Identify the digit in each place value column provided.
• Step 2: Write these digits according to their place values to construct the entire number.

Let's work through these steps:

Step 1: Let's identify the digits under the place value columns:

• Millions: No digit listed, so it's implicitly 0.
• Hundreds of thousands: 3
• Tens of thousands: 1
• Thousands: 0
• Hundreds: 5
• Tens: 0
• Units: 7

Step 2: We concatenate these digits in order of decreasing place value:

Hundreds of Thousands (3), Tens of Thousands (1), Thousands (0), Hundreds (5), Tens (0), Units (7).

Constructing the number, we get $310,507$.

Therefore, the number represented in the place value chart is $310,507$.
