Answer :

Sure, let's round the number 10.987 to the nearest tenth.

1. First, identify the tenths place and the number to the right of it. In the number 10.987, the tenths place is 9, and the number to the right of it, in the hundredths place, is 8.

2. To round to the nearest tenth, check the digit in the hundredths place (which is 8 in this case). According to rounding rules:
- If the hundredths digit is 5 or greater, increase the tenths digit by 1.
- If the hundredths digit is less than 5, leave the tenths digit as it is.

3. Since the hundredths digit here is 8 (which is greater than 5), you need to increase the tenths place digit (9) by 1.

4. Adding 1 to the tenths place digit (9) results in 10.9 turning into 11.0.

Thus, when rounding 10.987 to the nearest tenth, the result is 11.0.
