How do you put decimals in a word form?

First, write out the whole number until the decimal point. Next write 'and' for the decimal point. Finally, write out the value of decimal part of the number:

0.X is tenths

0.XX is hundredths

0.XXX is thousandths

0.XXXX is ten thousandths...and so on.

For example 13.4563 would be thirteen and four thousand five hundred sixty-three ten thousandths.
