Round 164 to nearest hundreth.
How did they get 12.81?
There must be something missing in your problem. Obviously 164 rounded to the nearest hundredth (or hundred) is not 12.81.
Unless there are typos, "164 to nearest hundredth"= 164.00.
13.87
12.81
To round a number to the nearest hundredth, you need to look at the digit in the thousandth place (the second decimal place). In this case, the digit in the thousandth place is 4.
To round it to the nearest hundredth, we follow these steps:
1. Look at the digit in the next decimal place (the hundredth place), which is 6. If the digit in the hundredth place is 5 or greater, we round up. If it is less than 5, we round down.
2. In this case, the digit in the hundredth place is 6, which is greater than 5. Therefore, we need to round up.
3. Add 1 to the digit in the thousandth place and drop all the digits to the right of the hundredth place.
4. By adding 1 to 4, we get 5. Therefore, the rounded number to the nearest hundredth is 164.05.
It seems there might have been a typo in the answer you provided (12.81), as that is not the rounded value of 164 to the nearest hundredth. The correct rounded value is 164.05.
