Calculate Percentages Instantly! →Understanding the Basics of 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 "15 percent," we mean 15 out of every 100.
Calculating Percentages Manually
While our calculator makes things incredibly easy, understanding the manual calculation can be helpful. Here's the basic formula:
Percentage = (Part / Total) * 100
Let's break this down with examples:
Example 1: Finding What Percent of a Number Is
Question: What is 15% of 200?
- Convert the percentage to a decimal: Divide 15 by 100, which gives you 0.15.
- Multiply the decimal by the total amount: 0.15 * 200 = 30
Therefore, 15% of 200 is 30. Skip this tedious work and use our tool!
Example 2: Finding What Percentage One Number Is of Another
Question: 30 is what percent of 150?
- Divide the part by the total: 30 / 150 = 0.2
- Multiply the result by 100: 0.2 * 100 = 20
So, 30 is 20% of 150. Or, use our tool and find out even faster!
Example 3: Calculating Percentage Increase or Decrease
Question: 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 * 100 = 25
Therefore, the increase from 80 to 100 is a 25% increase. Let our tool do it for you!
