write the number to different decimal place and significant figures 280.996 to 1 decimal place

Solution:
1. Given number: 280.996

2. To round to 1 decimal place, we consider the digit in the tenths place and the digit in the hundredths place.
- Tenths place digit: 9
- Hundredths place digit: 9

3. Since the hundredths place is 9 (which is 5 or greater), we round the tenths place up by 1.

4. New tenths place after rounding: 9 + 1 = 10, however, this affects the units place as well.

5. Since incrementing results in a carry over, 280.996 becomes 281.0 after rounding.

6. Thus, 280.996 rounded to 1 decimal place is:
281.0
