The place value columns after the decimal point, starting form the one immediately to the right of the decimal point and going right, are: tenths, hundredths, thousandths, ... thus as the 2 is in the third place value column after the decimal point, it is in the thousandths column and represents two-thousandths (2/1000).

Since it is a decimal, the 9 stands for tenths, the 5 stands for hundredths, and the 4 stands for ones. Going to the right -> behind the decimal point is tenths, hundredths, thousandths, and so one (there is no such thing as ones here). Going to the left <- in front of the decimal point is where ones, tens, hundreds, thousands, and so on begins.

The 9 is in the tenths column. Remember it's Hundreds, Tens, Ones, decimal, Tenths, Hundredths, Thousandths.
You write it as 0.004 because to the left of the decimal point is ones, to the first zero to the right of the decimal point is tenths, to the second zero to the right of the decimal point is hundredths, and so on.
0.505 = zero ones and five tenths and zero hundredths and five thousandths
