Calculate Percentages Now →Understanding Percentages
A percentage is simply a way of expressing a number as a fraction of 100. The word "percent" comes from the Latin "per centum," meaning "out of one hundred." So, when we say "25%," we mean 25 out of 100.
Three Common Percentage Problems
Most percentage questions fall into one of three categories:
- Finding what percent of a number is: For instance, what is 15% of 200?
- Figuring out what percentage one number is of another: For example, 30 is what percent of 150?
- Calculating percentage increase or decrease: Such as, going from 80 to 100 is what percentage increase?
Solving Percentage Problems Manually
While our calculator offers a quick solution, understanding the underlying math is helpful. Here's a breakdown of how to solve each type of problem:
1. Finding What Percent of a Number Is
To find what a certain percentage of a number is, convert the percentage to a decimal and multiply. For example, to find 15% of 200:
- Convert 15% to a decimal by dividing by 100: 15 / 100 = 0.15
- Multiply the decimal by the number: 0.15 * 200 = 30
- Therefore, 15% of 200 is 30.
2. Figuring Out What Percentage One Number Is of Another
To find what percentage one number is of another, divide the first number by the second and multiply by 100. For example, to find what percentage 30 is of 150:
- Divide the first number by the second: 30 / 150 = 0.2
- Multiply the result by 100: 0.2 * 100 = 20
- Therefore, 30 is 20% of 150.
3. Calculating Percentage Increase or Decrease
To calculate the percentage increase or decrease between two numbers:
- Find the difference between the two numbers: For example, going from 80 to 100, the difference is 100 - 80 = 20.
- Divide the difference by the original number: 20 / 80 = 0.25
- Multiply the result by 100: 0.25 * 100 = 25
- Therefore, going from 80 to 100 is a 25% increase.
