Explanation:

To round up or down you look at the place you are looking to round to (nearest ten thousandth) in this problem. Then you look at the digit to the right:

  • If the digit to the right is less than #5# you leave the place you are rounding the same and make all the digits to the right #0#.

  • If the digit to the right is greater than or equal to #5# you add #1# to the place you are rounding to the same and make all the digits to the right #0#.

In this problem the ten thousands are the #color(red)(5)# in the number:

#2color(red)(5)1,538#

The digit to the right is a #color(orange)(1)#.

#2color(red)(5)color(orange)(1),538#

Because the digit to the right is less than #5# we leave the place we are rounding to the same and make all of the digits to the right #0#;

#2color(red)(5)0,000#
