How to Find the Percentage of Two Numbers: A Simple Guide

Imagine you’re at a café, sipping your favorite brew, and someone asks you how to find the percentage between two numbers. It’s one of those questions that might seem daunting at first but is actually quite straightforward once you break it down. Let’s dive into this together.

First off, let’s clarify what we mean by “percentage.” At its core, a percentage is simply a way of expressing a number as a fraction of 100. So when we talk about finding the percentage between two numbers—say 50 and 100—we’re essentially trying to understand how much one number represents in relation to another.

To start with our example: if you want to find out what percentage 75 is between 50 and 100, here’s how you’d do it:

1. Identify Your Numbers: In this case, your smaller number (let’s call it A) is 50 and your larger number (B) is 100.

2. Calculate the Range: Subtract A from B:
   [
   \text{Range} = B – A = 100 – 50 = 50
   ]

3. Find the Part: Now subtract A from your target number (which here is C or our value of interest):
   [
   \text{Part} = C – A = 75 – 50 = 25
   ]

4. Calculate the Percentage: Finally, use these values in our formula for percentage:
   [
   \text{Percentage} = (\text{Part}/\text{Whole}) × 100%
   ] Plugging in our numbers gives us:
   [
   \text{Percentage} = (25/50) × 100% = (0.5) × 100% = 50%
   ] So there you have it! Seventy-five sits right at fifty percent between fifty and one hundred.

Now let’s switch gears slightly because percentages can also be used to determine changes over time—a common scenario whether you’re tracking sales figures or personal finances.

If you’re looking for how much something has increased or decreased—in other words, calculating "percentage change"—the process looks like this:

1. Determine Your Old Value and New Value: Suppose last month you earned $2,342 (Old Value), and this month it’s $2,500 (New Value).

2. Use This Formula for Percentage Change:
   [
   (\text{New Value} – \text{Old Value}) / |\text{Old Value}|
   ] Inserting our values yields:
   (
   =(2500-2342)/2342

   .06746
   ,
   which translates roughly into an increase of about (6.75%).
   If instead your earnings dropped from December ($2500) to January ($2425), you’d follow similar steps leading up to determining that decrease was approximately (3%).

And just like that—you’ve not only learned how percentages work but also gained insight into their practical applications!

Remember too that tools like Excel can make these calculations even easier with built-in formulas where all you’ll need are cell references rather than doing manual math each time; just type =(C2-B2)/B2 directly into any blank cell after entering your data points.

Finding percentages may initially feel tricky—but with practice—and perhaps while enjoying another cup of coffee—it becomes second nature! Whether measuring performance metrics or simply understanding relationships among numbers around us daily—the ability to calculate percentages opens doors across various fields—from finance to education—and beyond!
