How to round 0.998 to the nearest hundreth

1.0

Step-by-step explanation:

To round a this number to the nearest hundredth, you must look at the previous place value. The number previous to the hundredth place is 8, which is in the thousandth place value. Now lets look at the rounding rules which are the following:

If the previous number is 1, 2, 3, or 4, you round down If the previous number is 6, 7, 8, or 9, you round up If the previous number is 5 and the current number is even, you round down If the previous number is 5 and the current number is odd, you round up

Looking at rules, the number previous to the hundredth place is 8. By looking at the rounding rules, it round the current number up by one. If you round hundredth place's number up, 9⇒10. Since it becomes ten, we must round the next place value number, in this case which is the tenth place, up by 1. Rounding the tenth place's number up by 1, we get 9⇒10. Since it is an another 10, we round the next place value number up by 1 again. In this case we are rounding the one's place by 1. Therefore, we get 1.0.

Your final answer should be 1.0 if you follow the rounding rules.
