Calculating percentages can be an essential skill for many aspects of life, from determining discounts in stores to figuring out your final grade in school. Regardless of the reason, using a mobile calculator can make this process quick and easy. In this article, we will provide a step-by-step guide on how to calculate percentages with your mobile calculator.

Step 1: Open the Calculator App

Firstly, access your smartphone’s calculator app. Most smartphones come with a pre-installed calculator app that is easily accessible from the home screen or within the app drawer. If you don’t have one, you can download one from your device’s app store (such as Google Play Store or Apple App Store).

Step 2: Understand the Percentage Formula

Before calculating the percentage on your mobile calculator, it’s important to know how percentages work. The basic formula for calculating a percentage is:

Percentage = (Part / Whole) x 100

For example, if there are 50 apples and you have 15 apples, the percentage calculation will look like this:

Percentage = (15 / 50) x 100

Step 3: Input Numbers

Once you’ve opened your calculator app and understood the percentage formula, input your numbers. In our example, we’ll begin by inputting the part (15) followed by a division symbol (/), then inputting the whole (50).

On most mobile calculators, you’ll see your equation displayed as “15 ÷ 50.”

Step 4: Perform Division

After inputting the denominator and numerator values into the mobile calculator, press the equals button (=) to compute their division result.

For our example, after pressing “=”, you’ll see “0.3” displayed on the screen.

Step 5: Convert Decimal to Percentage

To convert the decimal result to a percentage, simply multiply it by 100. To do this, press the multiplication symbol (x) on your mobile calculator, input “100,” and then press the equals button again.

For our example, you’ll input “0.3 x 100” and then press “=”, displaying the result: “30.”

Step 6: Display the Final Percentage

The final calculation will give you the percentage in a numerical format. In our example, the result is 30, which means you have 30% of the apples.

Conclusion

By following these simple steps, you can quickly and easily calculate percentages using your mobile calculator. Whether you’re shopping for discounts or figuring out your exam score, having this skill on hand will surely prove useful in many situations.
