Calculate Percentages Instantly →Understanding Basic Percentage Problems
Before diving into the calculator, let's clarify the three main types of percentage problems:
- Finding a percentage of a number: What is X% of Y? (e.g., What is 15% of 200?)
- Finding what percentage one number is of another: X is what percent of Y? (e.g., 30 is what percent of 150?)
- Calculating percentage increase or decrease: What is the percentage change from X to Y? (e.g., What is the percentage increase from 80 to 100?)
Using a Calculator to Solve Percentage Problems
Most calculators, whether physical or on your phone, have a percentage (%) button. Here's how to use it for each type of problem:
1. Finding a Percentage of a Number
Example: What is 15% of 200?
- Enter the number:
200 - Press the multiplication button:
x - Enter the percentage:
15 - Press the percentage button:
% - On some calculators, the answer will appear immediately. If not, press the equals button:
= - The result:
30
Therefore, 15% of 200 is 30.
2. Finding What Percentage One Number Is of Another
Example: 30 is what percent of 150?
- Enter the first number:
30 - Press the division button:
/ - Enter the second number:
150 - Press the equals button:
= - The result will be a decimal (e.g., 0.2).
- Multiply the decimal by 100:
x 100 - Press the equals button:
= - The result:
20
Therefore, 30 is 20% of 150.
3. Calculating Percentage Increase or Decrease
Example: What is the percentage increase from 80 to 100?
- Find the difference between the two numbers:
100 - 80 = 20 - Divide the difference by the original number:
20 / 80 = 0.25 - Multiply the result by 100:
0.25 x 100 = 25
Therefore, the percentage increase from 80 to 100 is 25%.
