It is easy,simplify read it as possible
516.823 is read as five hundred sixteen and eight hundred twenty-three thousandths
The point here is that 2 is classified as the hundredths place.In which at the right side of it is 3 which is placed at the thousandths place
Simply round down 2 for 3 ≤ 5,change 3 to 0
So the final outcome is 516.820
That is the final answer.
I hope I helped you:)
