To round Anna's sample to the nearest hundredth, you'll want to focus on the two decimal places after the decimal point. Here's a step-by-step explanation of how to do it:
1. Identify the digit in the thousandth place, which is the third digit after the decimal point. In Anna's sample, let's say this digit is "X."
2. Look at the digit to the right of the thousandth place, which is the ten-thousandth place. In Anna's sample, let's say this digit is "Y."
3. If the digit "Y" is 5 or greater, you'll need to round up the digit in the thousandth place, "X." If "Y" is less than 5, you leave "X" as it is.
4. After determining whether to round up or not, replace "X" with the new rounded value.
5. The result is your rounded value, with two decimal places after the decimal point.
For example, let's say Anna's sample is 3.56789.
- The digit in the thousandth place is "6."
- The digit in the ten-thousandth place is "8."
Since "8" is 5 or greater, you'll round up the digit in the thousandth place. "6" + 1 = "7."
So, rounding Anna's sample to the nearest hundredth, it becomes 3.57.
