To round the number 3.39 to the nearest tenth, follow these steps:
- Identify the tenths place: In 3.39, the tenths place is the first digit after the decimal point, which is 3.
- Look at the hundredths place: This is the next digit after the tenths place, which is 9.
- Use the rounding rule: If the digit in the hundredths place is 5 or greater, round the tenths place digit up by 1. If it is less than 5, keep the tenths digit the same.
- Since the hundredths place is 9 (which is greater than 5), round the tenths digit 3 up to 4.
- Final rounded number: The tenths place becomes 4, so 3.39 rounded to the nearest tenth is 3.4.
