pencil.png Representing Decimals

What do you mean representing decimals?
When you represent decimals you're just saying the decimals in words, expanded, or standard form.

words

In decimal word form, you say the # before the decimal. After you do that, you say "and....."
and then your other #s after your decimal. After that you say what place the last # is only.
(see the example for help)

expanded

In expanded form, you break up the decimals in parts.So, it's pretty much the same thing as
skinnies, bits, and flats, just with decimals.(see the example for help)
