  1. Percentages are ratios that represent fractions of 100, so the word "percent" really means "per 100".
  2. The basic formula to calculate percentages is % = (Value ÷ Total Value) × 100.
  3. A value written as a percentage can also be written as a decimal or a fraction. For example, we know that a quarter is 25% but this can also be expressed as 0.25 or 25100 which reduces to 14.
