Question

The population of Santa Rosa, CA was last recorded as 179,213.

The city council wants to round the population to the nearest ten-thousand for a business brochure.
What number should they round the population to?

Answer 1

The population rounded to the nearest ten-thousand is 180,000

Explanation:

To round off to the nearest ten-thousand, we check what number is at the ten thousand place and what comes at the thousand place,

We get the following table,

So, at the ten thousand place, we get 7 and at the thousand place, we get 9

now, since 9 is greater than 5, we round up i.e, we add 1 to the ten thousand place, and get, 7 + 1 = 8,

so the population, rounded to the nearest ten-thousand is,

180,000
