Given:

The population is given as, P = 198,714.

The objective is to round off the digits and provide the required explanation.

Step-by-step explanation:

1. If the population is rounded to the nearest ten thousand,

`P=20,000`

2. The digit placed in the ten thousands place is 9.

3. To round off the the digit placed in ten thousand, then the digit present before it, which is in thousands place must be considered.

4. In the given number 198,714, the digit present in thousands place is 8.

5. If the preceding digit is 5 or greater than 5, then the digit required to round off will increase up by 1.

6. If the number 9 is rounded up, it will increase by 1 and become 10.

7. If the value of the place is 10 or more, insert the once value of the two digit number at the same place and add the tens value of the two digit number to the successive digit of the given place value.

8. Since, the current value placed in ten thousands is 9 and the preceding value in thousands is more than 5, then the value 9 will increase by 1 and become 10.

9. The number 198714 rounded to nearest ten thousand is, 20000.
