• For numbers over a multiple of ten
• If you have .57, put 57 over 100 because .57
  reaches to the 100ths place.
• If the number is .824, put 824 over 1000 and put
  into simplest form.

Changing Decimals, continued

• Simplest Form
• divide both the top and bottom by the greatest
  common factor.
• Example For 50/100, you would take both the
  numerator and denominator divided by 50 to get
  1/2.

• Make sure that the numerator and denominator have
  no common factors
