If you’ve ever encountered a situation where you needed to determine a percentage value, you know how stressful it can be. Common pain points include figuring out the formula to use, ensuring that the inputs are accurate, and converting the result to a useful format. But by breaking the process down into manageable steps, you can eliminate these pain points and calculate percentages with ease.
So, how do you calculate percentage from 2 numbers? The first step is to determine the value you want to calculate as a percentage of the total. For example, if you want to find out what percentage of students passed a test, you would divide the number of students who passed by the total number of students. Then, you would multiply the result by 100 to get the percentage value. The formula for this calculation is:
Percentage = (Value ÷ Total) x 100%
Breaking It Down
Let’s look at a real-world example. Say you’re a teacher and you want to know what percentage of your students passed a recent exam. Out of 30 students in your class, 24 passed the exam. Here’s how you would calculate the percentage:
- Divide the value you want to calculate as a percentage of the total (24) by the total (30): 24 ÷ 30 = 0.8
- Multiply the result by 100 to get the percentage value: 0.8 x 100% = 80%
So, 80% of your students passed the exam.
