  • Percentage of One Number to Another: (Part / Whole) * 100 = Percentage
    Example: 30 is what percent of 150? = (30/150) * 100 = 20%
  • Percentage Increase/Decrease: ((New Value - Old Value) / Old Value) * 100 = Percentage Change
    Example: Percentage increase from 80 to 100 = ((100-80) / 80) * 100 = 25%
