Answer:
people
Step-by-step explanation:
Given
US Population in 2014: About 318,900,000
Required
Approximate
From the given options, it's seen that the population of US is to be approximated to one significant digit and the result should be presented in standard form
So, the first step is to write out the population
<em>318,900,000</em>
As a general rule,
Category 1: Digit 0-4 are approximated to 0
Category 2: Digit 5-9 are approximated to 1
Since, we are approximating to one significant digit, only the first digit is needed, others are to be approximated.
The first digit is 3, meaning that approximation starts from the next digit which is 1
Approximating <em>318,900,000 </em>will give <em>300,000,000 </em>because "1" falls in category 1 as illustrated above.
The final step is to convert <em>300,000,000 </em>to standard form.
There are 8 0s after 3.
Hence,
Conclusively, the approximation of 318,900,000 is people
