Objective – 2) to write decimals in expanded form.
Expanded Form
Write the number that appears before the
decimal point in expanded form.
For decimals, place a zero in the ones
place.
Also, substitute zeroes for all spaces after
the decimal point that come before the
digit that you are working with.
Example: Write 13.361 in expanded form.
Remember, deal with the number before
the decimal first.
10 + 3 + 0.3 + 0.06 + 0.001
Then, do the decimal part.
From Words to Standard Form
Read everything that comes before the
word “and.” Write that number down.
Place a decimal point at the word “and.”
Read the last word of the sentence to see
how many decimal places you need.
Fill in the decimal places with your
number. Fill in as far to the right as
possible, and use zeroes to fill any
empty spaces.
Example
Write the following number in standard form:
two hundred six and fifty-four ten-thousandths
0 __
0 __
5 4
206 . __
__
The word “ten-thousandths” indicates
that we need four decimal places.
When we clean it up, the answer is 206.0054
