Question

Round the following number to the nearest thousandth. 455.2187

Answer 1

455.219

first of all we need to know our place values.

4= hundreds

5= tens

5= units/ones

2= tenths

1= hundredths

8= thousandths

7= ten thousandths.

To round a number to the nearest thousandth, look at the next place value to the right (the ten thousandths). If it's 4, or less, just remove all the digits to the right. If it is 5 or greater, add 1 to the digit in the thousandths place and then remove all the digits to the right.

Now to your question; the ten thousandths digit is greater than 5 (7). So we would add 1 to the digit in the thousandths place ( which is 8) then remove all digits to the right.

So our result end up in :

455.219
