  • From Words to Standard FormRead 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 as far to the right as possible with your number, then use zeroes to fill any empty spaces.

  • Example: Write the following number in standard form:

    two hundred six and five thousandths206.The word thousandths indicates that we need three decimal places.__ __ __ 5 0 0When we clean it up, the answer is 206.005

  • Lets Practice: Six hundred fifty-three and twenty-three hundredths

    Fourteen and five tenths

    Three thousand, nine hundred thirty-five and sixty-one thousandths

  • Expanded FormWrite the number that appears before the decimal point in expanded form.For numbers that are decimals only, 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 + 3Then, do the decimal part.0.060.3+++0.001
