Sure! To round the number 23.49 to one decimal place, follow these steps:
1. Identify the digit in the first decimal place, which is the tenths place. In 23.49, this digit is 4.
2. Look at the digit in the second decimal place (the hundredths place) to decide whether to round up or keep the digit the same. In 23.49, this digit is 9.
3. If the digit in the hundredths place is 5 or greater, you round up the tenths place digit by 1. If it is less than 5, you keep the tenths place digit the same.
4. Here, the digit in the hundredths place is 9, which is greater than 5. Therefore, you round up the tenths digit from 4 to 5.
