To round the number 7.28 to the nearest tenth:
- Identify the digit in the tenths place. For 7.28, the tenths place is 2.
- Look at the digit to the immediate right of the tenths place (the hundredths place), which is 8.
- If this digit is 5 or greater, increase the tenths digit by 1. Since 8 >= 5, increase 2 by 1 to get 3.
- Replace all digits to the right of the tenths place with zero or remove them, so the number becomes 7.3.
Therefore, 7.28 rounded to the nearest tenth is 7.3.
