It is important to remember that the fourth digit after the decimal point is in the ten-thousandth place.

Then, given the following number:

`398.574986215`

You can follow these steps in order ti round it to the nearest ten-thousandth:

1. You can identify that the digit in the ten-thousandth place is:

`9`

2. Identify the digit to the right of
`9`. This is:

`8`

3. Since:

`8>5`

You must round up. Increase the digit
