13. Example: Write 13.361 in expanded form. Remember, deal with the number before the decimal first. 10 + 3 Then, do the decimal part. 0.060.3 + 0.001 ++

14. 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.
