how can i round each number to the place of the underlined digit?
An underlined digit usually means that the digit is significant, and in general, it is a trailing zero, i.e. a zero at the end of a number. Most of the time there would be no more digits following the underlined digit.
Could you post an example of the question you are trying to do?
To round each number to the place of the underlined digit, follow these steps:
1. Identify the underlined digit. This is the digit that determines the place value to which you want to round the number.
2. Look at the digit to the right of the underlined digit. This is the digit that will help determine if rounding up or down is necessary.
3. If the digit to the right of the underlined digit is less than 5, you round down. This means you keep the underlined digit and any digits to the right of it as they are.
4. If the digit to the right of the underlined digit is 5 or greater, you round up. This means you increase the value of the underlined digit by 1 and truncate any digits to the right of it.
Let's look at an example to understand this better:
Example: Round each number to the place of the underlined digit.
1. Number: 34.561
Underlined digit: 6
Digit to the right: 1 (which is less than 5)
Rounding: Round down
Rounded number: 34.56
2. Number: 86.973
Underlined digit: 9
Digit to the right: 7 (which is greater than 5)
Rounding: Round up
Rounded number: 86.98
Remember to always pay attention to the digit to the right of the underlined digit, as it determines whether you round up or down.
