Decimals in expanded form review

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

Expanded form

Expanded form is a way to write numbers by adding the value of its digits.
We can use a place value chart to think of the value of a number's digit.

Example

Let's write 3.405 in expanded form.
Ones.TenthsHundredthsThousandths
3.405
3.405=3 ones +4 tenths+ 0 hundredths+5 thousandths
3.405=(3×1)+(4×110)+(0×1100)+(5×11000)
3.405=3+410+0+51000
3.405 in expanded form is 3+410+51000.
