In the number 51,309,487, what is the value of the 3?

If we write the number in a place value chart, we can see the 3 is in the hundred thousands column, so it represents 300,000.

In the number 51,309,487, which digit is in the ten millions place? 

Again, looking at the chart above, 5 is in the ten millions column. So the 5 represents 50,000,000.

Let's try these questions to see what else we know about place value.
