How Can I Calculate Percentage in Calculator?

Understanding Basic Percentage Problems

Before diving into calculator techniques, let's clarify the common types of percentage problems you might encounter:

• Finding a percentage of a number: What is 15% of 200?
• Determining what percentage one number is of another: 30 is what percent of 150?
• Calculating percentage increase or decrease: What is the percentage change from 80 to 100?

Calculating Percentages with a Standard Calculator

Most standard calculators, whether physical or on your phone, have a percentage (%) button. Here's how to use it:

1. Finding a percentage of a number:
   • Enter the number you want to find the percentage of (e.g., 200).
   • Press the multiplication (*) button.
   • Enter the percentage (e.g., 15).
   • Press the percentage (%) button.
   • Press the equals (=) button. The display will show the result (30).
2. Determining what percentage one number is of another:
   • Enter the first number (e.g., 30).
   • Press the division (/) button.
   • Enter the second number (e.g., 150).
   • Press the equals (=) button.
   • Multiply the result by 100 (either manually or using the calculator's memory function if available). The display will show the percentage (20).
3. Calculating percentage increase or decrease:
   • Determine the amount of increase/decrease (e.g., 100 - 80 = 20).
   • Divide the change by the original amount (e.g., 20 / 80).
   • Press the equals (=) button.
   • Multiply the result by 100 (either manually or using the calculator's memory function if available). The display will show the percentage change (25).
