I want to know how to round 2.49 to the nearest hundredth I know the answer but I need to know how to do it to show my work.

Answers

Answer is 2.49 which you said you knew.

When you round up to hundredths, your goal is to determine if the number 2 places to the right of the decimal (hundredths) will get bigger or stay the same. The rule is if the number to the right is 5 or bigger, you raise the hundredth place by 1. If the number is 0-4, leave it alone, no change.

Take this example, 2.48765.

The “8” is the hundredths place. Does it get bigger or stay the same? Look at the number to the right of 8, it is a 7. If the number is 5 or bigger, you raise it by 1. So your number becomes 2.49

Try it again. Let’s say your number is 2.49123, we are looking at hundredths place again, so we are looking at the 9. Is the number to the right 5 or bigger? No, it is 0-4 so it does not change. Your number remains 2.49.

This works for any place, tenths, hundredths, thousandths, etc. Find your number that will change or stay the same, look to the number to the right and find out if it changes or not.
