What is 0.997 rounded to 1 decimal place?

Answer 1

One decimal place indicates that the answer will have one digit after the period. Because we have more than one digit in the orginal answer, we look at the digit to the right of the first decimal place (the decimal place we want the answer reported to) to see how we are going to report the answer to one decimal place. Because it is a 9, we round up the first decimal place. The answer is 1.0 .
