Convert Between Place Values

To convert between place values, remember the following relations:

1 ten = 10 ones
1 hundred = 10 tens
1 thousand = 10 hundreds
1 ten thousand = 10 thousands
1 hundred thousand = 10 ten thousands

For example, consider the following equation.

_____ hundreds = 5,000 ones

Let's find the missing number in this equation.

We have:

1 hundred = 10 tens

             = 100 ones

Now, find the number of hundreds in 5,000 ones. Count by hundreds.

50 hundreds = 5,000 ones
