What is 832.248 rounded to the nearest tenth? a. 830 b. 832.2 c. 832.25 d. 832.3

I believe the answer is D. This is because a HTU chart would show that the second 2 is in the tenths column.

HTU.THT 
832 .248
 
This means that we need to pay attention to the 2 and that this should only go to one decimal place. 

8 rounds up, so we add one onto the 4 to make 5. We now have 832.25
5 rounds up so we add one onto the 2 to make 3. We now have 832.3

We only need it to one DP so this is the answer.
 
(I think this is right, it's been a long time since I have been oing things at this level. I feel old. I hope this helped!)
