#139664# rounded to the nearest ten is #139660#.

Explanation:

When rounding, you look at the digit to the immediate right of the digit to be rounded. If that digit is five or greater, round up. If that digit is four or less, the digit to be rounded remains the same. Any digits after that digit become zeros, or drop-off if they're located after the decimal point. This is called rounding down.The breakdown of #139664# is:

#"1 hundred thousands"#
#"3 ten thousands"#
#"9 thousands"#
#"6 hundreds"#
#color(red)("6")" tens"#
#color(green)("4")" ones"#

The digit to the immediate right of the #6# in the tens place is #4#. Therefore, the #6# in the tens place remains the same, and the #4# is rounded down to #0#.

Therefore, #139664# rounded to the nearest ten is #139660#.
