To estimate how many more people live in atherton than needles, which is closer to exact answer : rounding to hundreds or thousands? Explain.
I assume you're asking about two cities in California, not Wisconsin or Australia.
Their populations are small -- so round to hundreds.
To estimate how many more people live in Atherton than Needles, it is generally more accurate to round to the thousands. Rounding to the hundreds may provide a rough estimate, but rounding to the thousands gives a slightly closer approximation.
Here's how you can go about estimating using rounding:
1. Find out the population of Atherton and Needles. Let's say Atherton has a population of 20,000 and Needles has a population of 5,000.
2. Subtract the population of Needles from Atherton: 20,000 - 5,000 = 15,000.
3. Now, you can round the difference to the nearest hundreds: 15,000 rounded to the nearest hundreds is 15,000.
4. Alternatively, you can round to the nearest thousands: 15,000 rounded to the nearest thousands is 20,000.
If you were to round to the hundreds, you would estimate that there are 15,000 more people in Atherton than Needles. But by rounding to the thousands, the estimate increases to 20,000. This gives a slightly closer approximation, considering the size of the difference.
Keep in mind that these are just estimates, and the actual population difference may be different. When it comes to estimating populations, rounding to the thousands provides a more refined approximation.
