Calculating percentages is a common task, and if you don’t have the formula memorized, using a calculator can be a handy tool. Whether you’re a student, business professional, or simply need to calculate a discount or tip, we’ve got you covered. In this step-by-step guide, we’ll show you how to calculate percentages using a calculator.

Step 1: Determine the two values you need

In order to calculate a percentage, you’ll need two values – the given number and the comparative number. For example, if you want to find out what percentage 75 is of 100, then 75 is the given number and 100 is the comparative number.

Step 2: Divide the given number by the comparative number

Once you have the two values, divide the given number by the comparative number. In our example, divide 75 by 100. This can be done on most calculators by simply entering 75 ÷ 100.

Step 3: Multiply the result by 100

The result from the previous step will be a decimal number. To convert it into a percentage, multiply the decimal by 100. For instance, if the result is 0.75, multiply it by 100 to get 75%.

Step 4: Round the final percentage (optional)

Depending on your needs, you may want to round the percentage to a whole number or a specified number of decimal places. This step is optional but can be useful in many situations.

Example:

Let’s take an example to put these steps into practice. Suppose you want to calculate what percentage 45 is of 60:

  • Step 1: The given number is 45 and the comparative number is 60.
  • Step 2: Divide 45 by 60. The result is 0.75.
  • Step 3: Multiply 0.75 by 100 to get 75%.

Therefore, 45 is 75% of 60.

Calculating percentages is now a breeze with a calculator. Follow these steps and you’ll be able to calculate percentages accurately and quickly in various scenarios. Whether you’re determining a discount, analyzing data, or solving mathematical problems, this guide has got you covered.

So, next time you encounter a percentage calculation, don’t fret – pull out your calculator and follow these straightforward steps.
