How can I determine what a number is a percentage of another number?

by

To determine what a number is a percentage of another number, you can follow a simple mathematical formula. Let’s break it down step by step:

  1. Identify the percentage and the base number: First, clearly define the percentage you want to find and the base number (the number you think it might be a percentage of).
  2. Convert the percentage to its decimal form: Divide the percentage by 100. For example, if you have 25%, you would calculate it as:

    3. Decimal = 25 / 100 = 0.25

  3. Set up the equation: To find the base number (X) that corresponds to your percentage, you can set up the equation like this:

    4. Percentage = (Decimal) × (Base Number)

  4. Rearrange the equation to solve for the base number: This is done by dividing the percentage by the decimal you calculated earlier:

    5. Base Number (X) = Percentage / Decimal

  5. Perform the calculation: Plug your numbers in and calculate the base number. For instance, if you want to find out what 25 is a percentage of, you would set it up like this:

    6. X = 25 / 0.25 = 100

  6. Interpret your result: In this case, 25 is 25% of 100. You can confirm this by multiplying 100 by 0.25, which brings you back to 25.

This method can be applied to any numbers. Just remember, the key is to convert the percentage into a decimal before you set up your equation. With practice, you’ll find it a straightforward process!
