Percentage: key points

A percentage is a fraction with 100 as its denominator; x% means x parts out of every hundred.

  • x% of N = x × N / 100.
  • A as a per cent of B = A / B × 100.
  • Number = given value × 100 / given per cent.
  • A rise of a% followed by a fall of b% gives a net change of (a − b − ab/100)%.
