The answer is A.
When you are looking at a decimal, the ones place is right before the decimal point, and as you go up in numbers, you go through the tens, hundreds, thousands, ten-thousands, etc. The same goes for decimals. As you start going to the right of a decimal point, the first one is in the tenths, then hundredths, then thousandths, ten thousandths, and etc. So the answer is A. because the decimals go into the 10,000ths.
