Answer:
217.703
Explanation:
From the decimal you have tenths, hundredths then thousandths so you need to round to the 3rd decimal place. The 4th decimal place is greater than 5 so you would round the thousandths place up to 3.
The thousandth place is the third digit to the right of the decimal point. Since the number on the ten thousandth place is greater than 5, then the number on the thousandth place (which is 2) is rounded up to 3.
