• Quick Percentage Calculation
• You can flaunt your percentage calculation skills
  by knowing some
• simple math tricks. The simplest and the fastest
  way to calculate
• percentage is by multiplying the numbers first.
  Then you can think over
• the two decimal places. You must remember that
  percent implies a
• fraction out of 100. Thus, you need to move the
  decimal two places left
• of the result. For example
• 20 percent of 70 ? Multiply 20 with 70 which is
  1400. Now, move the
• decimal two places left, so the answer is 14.
• If you have to calculate the percentage of some
  number like 72 or 29,
• then round up the number to the nearest multiple
  like 70 30. This
• will help you in getting a quick approximate
  value.
