To round 5.331 to the nearest tenth, you look at the digit in the hundredths place, which is the second digit to the right of the decimal point. In this case, the number is:
- The tenths place is 3 (the first digit to the right of the decimal).
- The hundredths place is 3 (the second digit to the right of the decimal).
Since the hundredths place (3) is less than 5, you will round down. Therefore, 5.331 rounded to the nearest tenth is 5.3.
