Fourteen and twenty-eight hundredths
Six hundred and forty-one thousandths
First, you take a number for example 2.3 in words this is two and ( the "and" stands for decimal) three tenths. The standard form is actually 2.3, the expanded form is 2 + 0.3. It's as easy as pie! Also after the decimal all the numbers are less than 1 and their names go like this from left to right: Tenths( the closest one to the decimal) hundredths, thousandths, ten thousandths , hundred thousandths and you get the picture once you learn this it's super easy to deal with decimals:)
