There is no number. 100 is the only one that has a hundreds digit. It's impossible.
The hundreds place is three to the left of the decimal point; in 438217.065 it is the 2.
In the hundreds place, the digit "3" represents a value of 300. In the decimal system, each place value represents a power of 10, with the hundreds place being 10^2 or 100. Therefore, when the digit "3" is in the hundreds place, it signifies three hundreds, or 300.
All whole, three-digit numbers from 450 through 549 (when rounding to the nearest hundreds).
The number is three hundred eighty-two. Therefore, the 3 is in the hundreds place.
