Round to the nearest thousandth: 43,280.012498?

Question

Round to the nearest thousandth: 43,280.012498?

Answer 1

This is the same as rounding to the third decimal place.

First throw away all but four digits after the decimal point, ie one more than you want.

Then if the last digit is 0..4, just throw it away.

If the last digit is 5..9, throw it away and add 1 to the digit before it.

So in this case the answer is 43,280.012

If it was to four places, it would be 43,280.0125

Answer 2

43,280.012498

You look for the thousandths place, which is the number 2 after the decimal. Look at the number after 2, it is a 4, because it is a 4, you get rid of that 4 and all the numbers after it. Here's a reference:

If the place you are rounding at has the numbers 0-4 after it, get rid of that number and the ones after it's place, although, if it is either numbers 5-9, you add 1 to the decimal place you are rounding for. The decimal place means tenths, hundredths, thousandths, etc.

In your case, you are rounding off for the 2, since there's a 4 after the 2, get rid of it and all the numbers after it as so: 43,280.012

That is your final answer.
