Final answer:
To round to the nearest tenth, look at the hundredths place to determine if you round up or down. Numbers like 10.75, 10.80, and 10.84 all round to 10.8 since they're within the range that rounds to the nearest tenth as 10.8.
Step-by-step explanation:
When rounding to the nearest tenth, numbers that fall between 10.75 and 10.84 would round up or down to 10.8. The reason for this is that the digit in the hundredths place determines whether the tenth place rounds up or stays the same. If the hundredths place is 5 or greater, we round up. If it's less than 5, we round down. So, three numbers that round to 10.8 when rounded to the nearest tenth could be:
- 10.75 (rounds up to 10.8 because the hundredths place is 5)
- 10.80 (already at 10.8)
- 10.84 (rounds down to 10.8 because the hundredths place is 4)
Remember, the answer, rounded, is the same for these numbers when you round to the nearest tenth.
