What is percentage
  • A percentage is a number or ratio expressed as a
    fraction of 100. It is often denoted using the
    percent sign, as in 45 (read as "forty-five
    percent"). In mathematics, it is defined as the
    difference between a number and 100 divided by
    the number . In most contexts, a percentage is a
    number between 0 (zero) and 100.

What is percentage calculator
  • A percentage calculator is a tool used to
    calculate a percentage of a given number. This
    percentage calculator is useful for students in
    math classes, such as Algebra and Trigonometry,
    and also for those who simply want to know the
    answer to "how much is a certain percentage of
    something".

More example of percent
  • If 25 of 100 is 25, then 25 of 200 should be 2
    times 100, or 2 x 25, which is 50. Now that we
    have a basic understanding of what happens when
    calculating percentages, we may come across a
    formula. Note that in the last example we start
    with a real number greater than 1, and by
    shifting two decimal places, we calculate a
    formula greater than A percent value of 100.
    Again, we can use the standard formula to find
    the percent value (W) base value. (G) x
    percentage (P) / 100.

  • X is what percent of Y ?
  • Ans (X/Y) 100
  • What is the percentage increase/decrease ?
  • Ans (Y - X)/X 100
