#270,000#

Explanation:

When you round to the nearest ten thousand, your answer will be a multiple of ten thousand.

Identify the ten thousand place holder it is the fifth digit from the right.

The number will be #color(red)(??)0,000#

But before you just discard the other digits and replace them with #0#s, you need to decide whether you will round up or down.

Look at the digit in the thousands place #color(red)(??)color(blue)(0),000# - If it is #5# or more, round up, if it is #4# or less, the ten thousand value stays the same.

In this case we have #color(red)(26)color(blue)(5),427#

The thousands place value is #color(blue)(5)#, so the #color(red)(6)# will become #color(red)(7)#

The digits which follow are all #0#

#color(red)(27)color(blue)(0),000#

If the number had been: #color(red)(26)color(blue)(3),427#, then the rounded value would be

#color(red)(26)color(blue)(0),000#
