Since 2 is there in the ten thousandths place, we leave “2” as is. The answer is #color(blue)(1.736)#

Explanation:

When rounding to a place to the right of the decimal point, drop all.

Example 1. Round 7,803 to the nearest hundred.Since there is a "0" in the tens place, we leave the "8" as is. The answer is 7,800.

Example 2. Round 7,802.45123 to the nearest thousandth.
Since there is a "2" in the ten thousandths place, we leave the "1" as is. The answer is 7,802.451.

Required #color(red)(1.73629# to be rounded to the nearest thousandth.

Since 2 is there in the ten thousandths place, we leave “2” as is. The answer is #color(blue)(1.736)#
