How to Calculate Percentage of a Number

What is the formula for calculating a percentage of a number?

Choose the correct formula:

  1. A. (Percentage / 100) * Number
  2. B. (Number / 100) * Percentage
  3. C. (Number * Percentage) / 100

Answer:

Option C is the correct formula: (Number * Percentage) / 100

To calculate the percentage of a number, you can use the formula: (Number * Percentage) / 100. This formula involves multiplying the number by the percentage value and then dividing by 100 to get the result. Let's take an example to illustrate this:

If we want to find 25% of 80, we can use the formula as follows:

(80 * 25) / 100 = 2000 / 100 = 20

So, 25% of 80 is 20. By using the correct formula, you can easily calculate the percentage of any number.
