Expanded Form
Expanded form is a way to write a number to show the value of each digit, representing it as a sum of its place values, such as 433 = 400 + 30 + 3. This process helps to break down a number, making it easier to understand the individual contribution of each digit based on its position (ones, tens, hundreds, etc.).

 
How to Write a Decimal in Expanded Form
When writing a number in expanded form, you treat the decimal point as the divider between whole numbers (multiples of 10) and decimal numbers.
 
Example:
Write Each Value as a Term in an Addition Sentence
Once you have the value of each non-zero digit, you simply connect them all with plus signs.
485.609=400+80+5+0.6+0.009
