find percentage difference between two numbers

At some point in your life, you’ll probably need to find the percentage difference between two numbers. Whether you’re comparing prices at the grocery store or trying out different combinations of ingredients in a recipe, being able to find percentage difference between two numbers can be very useful. In this blog post, we’ll show you how to do it—and explain why it’s important. Read on.

Why It’s Important to Know

  • There are many situations in which knowing how to find the percentage difference between two numbers can be very useful. For example, let’s say you’re comparing prices on a pair of shoes. The first pair costs $100, and the second pair costs $120. Which pair of shoes is the better deal?
  • To answer that question, you need to calculate the percentage difference between the two prices. In this case, the percentage difference is 20%. This means that the second pair of shoes is 20% more expensive than the first pair.
  • Based on this information, you can decide whether or not the second pair of shoes is worth the extra cost.

The process of calculation

There’s a simple formula for calculating the percentage difference between two numbers: 

Percentage change = (amount of change / starting number) x 100

For example, let’s say you want to find the percentage difference between 10 and 15. 

In this case: 

percentage change = (5 / 10) x 100 = 50% 

This means that there has been a 50% change between 10 and 15. 

You can also use this formula to calculate the percentage decrease between two numbers. For example, let’s say that you want to find the percent decrease from 15 to 10. 

In this scenario: 

percentage change = (5 / 15) x 100 = 33.33% 

This means that there has been a 33.33% decrease from 15to 10. 

3 Easy Tips for Calculating the Percentage Difference Between Two Numbers 

  1. Use a calculator (or a pen and paper) to do the math for you. Trying to do complex equations in your head can lead to mistakes being made. 
  2. Write down each step of the calculation as you go along. This will help you keep track of where you are in the process and avoid making any mistakes. 
  3. If you’re not sure whether you’ve calculated the percentage correctly, try plugging your answer back into the formula to check your work. For example, if you want to find out what 20% of $100 is, you would calculate 100 x 0 .2= 20 . You can check your work by plugging 20 back into the equation like this:20/100=0 .2, which proves that your original calculation was correct. 

Conclusion:

As you can see, finding the percentage difference between two numbers is a fairly straightforward process. However, it’s also an important skill to be mastered if you want to be able to make informed decisions when comparing different values. Hopefully, this blog post has given you a better understanding of how to perform this calculation and why it can be so useful in everyday life.
