What is 22,119 rounded to the nearest hundred?

To round a number to the nearest hundred, you need to check the digit in the tenth position (the position right after the hundred position).
If the number in the tenth position is less than 5, then you convert all the digits after the hundred to zeros
If the number in the tenth position is equal to or greater than 5, then you will add one to the hundred and convert all digits after the hundred to zeros.

Applying this to the given number:
The number is: 22,119
The digit in the hundred position is: 1
we check the digit next to it (the tenth position): It is "1" which is less than 5
so, we just convert all digits after the hundred to zeros
Therefore, 22,119 to the nearest hundreds is 22,100
