Hello there!!
The answer to your question would be 500!!
We can figure this out by using the simple rule “ 5 or less round down, 5 or more round up”.
When given a certain value to round, you are going to want to look at the value that comes before it (in this case the tenths place).
Then you are gonna want to see if that number is 5 or more or 5 or less.
In this case, the number before the hundredth place is 0, which is less than 5, so we are going to round down, which gives us our answer which is 500!
I hope this helped!! If you have any further questions please feel free to ask! :-)
