See the solution process below:

Explanation:

The ten thousandth spot is two digits to the left of the comma:

#2color(red)(4)7,919#

If the digit in the thousand position (just to the left of the comma) is greater than or equal to #5# we need to add #1# to the digit in the ten thousand spot and change all of the digits to the right to #0#.

If the digit in the thousand position is less than #5# we just need to change all of the digits to the right to #0#.

For this problem, the digit in the ten thousand position is a #7# which is greater than or equal to #5# so we need to add #1# to the digit in the ten thousand spot and change all of the digits to the right to #0#.

#2color(red)(4)7,919 => 2color(red)(5)0,000# rounded to the nearest ten thousand.

See below

#250,000#

Explanation:

To round 247,919 to the nearest ten thousand, find the number in the #10,000# place which is the #4#

Next look at the number one place to the right to see if you need to round up. This number is a #9#. When numbers are #5# or greater, the place immediately to the left (ten thousands place), needs to increase by one.

Each of the digits to the right are changed to #0#.

This would make the number #250,000#
