To round 19.751 to the nearest tenths, we follow these steps:
1. Identify the tenths place: In the number 19.751, the digit 7 is in the tenths place.
2. Look at the digit in the hundredths place: The digit after the tenths place is in the hundredths place. In 19.751, this digit is 5.
3. Apply the rounding rule:
- If the hundredths digit is 5 or greater, we round up the digit in the tenths place by 1.
- If the hundredths digit is less than 5, we leave the tenths place digit as it is.
Since the hundredths place digit is 5, we round up the tenths place digit (7) by 1.
4. Adjust the rest of the number:
- The number 19.751 becomes 19.8 when we round 7 up to 8.
Therefore, the number 19.751 rounded to the nearest tenths is 19.8.
