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 you see 25%, it means 25 out of 100.
Percentages help us understand proportions and make comparisons. For instance, saying "80% of students passed the test" is easier to grasp than saying "80 out of every 100 students passed the test."
Common Percentage Problems
Many percentage problems fall into one of three categories:
- Finding what percent of a number is: 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?
Solving Percentage Problems Manually
While our calculator makes things simple, it's helpful to understand the underlying math. Here's how to solve these problems manually:
- Finding a percentage of a number: Convert the percentage to a decimal (divide by 100) and multiply. For example, 15% of 200 is (15/100) * 200 = 0.15 * 200 = 30.
- Finding what percentage one number is of another: Divide the first number by the second and multiply by 100. For example, 30 is what percent of 150? (30/150) * 100 = 0.2 * 100 = 20%.
- Calculating percentage change: Find the difference between the new and old values, divide by the old value, and multiply by 100. For example, the percentage change from 80 to 100 is ((100-80)/80) * 100 = (20/80) * 100 = 25%.
