# Decimals in written form review

Review writing decimals in written form, and try some practice problems.

## Written form

Written form is a way to write numbers using only words.

### Example

Let's write $\blueD3.\purpleD40\maroonD5$ in written form.
Ones.TenthsHundredthsThousandths
$\blueD3$.$\purpleD4$$0$$\maroonD5$
$3.405=\blueD{3}\text{ ones}+\,\purpleD{4}{0}\maroonD5\text{ thousandths}$
First, we will read the number to left of the decimal.
$\blueD{\text{Three}}$
Then, we read the decimal as "$\text{\goldD{and}}$".
$\blueD{\text{Three}} \goldD{\text{ and}}$
Finally, we read the numbers right of the decimal and state the place value of the digit farthest to the right.
$\blueD{\text{Three}}\goldD{\text{ and}}$ $\text{ \purpleD{four} hundred \maroonD{five} thousandths}$
$3.405$ in written form is three and four hundred five thousandths.
