Answer :
Final answer:
To round 97.8 to the nearest tenth, you evaluate the hundredths place. Since 97.8 is already at the tenths place with a 0 in the hundredths place, it remains 97.8 after rounding to the nearest tenth.
Explanation:
The student is asking to round 97.8 to the nearest tenth. To do this, you look at the number in the hundredths place, which is 8 in this case. Since 8 is greater than 5, you round up the digit in the tenths place. The number 97.8, when rounded to the nearest tenth, would be 97.8 as it is already at the tenths place and does not need any change.
For example, when adding two numbers with different levels of precision, such as 137.3 at the tenths place and 70.90 at the hundredths place, the final answer should match the least precise measurement after the calculation.
As a practice example, the sum of 137.3 s and 70.90 s equals 208.20 s. Following the same ruling of precision, this sum should be rounded to the tenths place, based on 137.3 s, to give a final answer of 208.2 s.
Answer: it is already rounded to the
If you mean the nearest tenths then the answer is 97.8 but if you mean the nearest tens then the answer is 100 hope this helps :)
