Whether you’re figuring out a test score, comparing prices, or calculating tips, knowing how to find the percentage of two numbers is super useful. And guess what? It’s actually really easy! Let’s break it down with simple steps and fun examples.
🧮 The Formula You Need
To find out what percentage one number is of another, just use this formula:
(Part ÷ Whole) × 100 = Percentage
Here:
- Part is the smaller number (the portion you’re measuring)
- Whole is the bigger number (the total or full amount)
🍕 Example 1: Pizza Time
Let’s say you ate 3 slices of an 8-slice pizza. What percentage did you eat?
(3 ÷ 8) × 100 = 37.5%
So you ate 37.5% of the pizza. Not bad!
📚 Example 2: Test Score
You got 18 questions right out of 20. What’s your score in percentage?
(18 ÷ 20) × 100 = 90%
Boom! You scored 90% on your test. Well done!
💸 Example 3: You Saved Money
A jacket originally costs $80, and it’s now $60. What percent discount is that?
Step 1: Subtract to find the amount saved:
$80 – $60 = $20
Step 2: Use the formula:
(20 ÷ 80) × 100 = 25%
So you got a 25% discount—nice find!
🧠 Quick Tips
- Always divide the part by the whole.
- Then multiply by 100 to turn it into a percentage.
- Don’t forget to round the result if needed!
✅ Practice Problems
Try these on your own:
- What percentage is 5 out of 25?
- You read 120 pages out of a 300-page book. How much have you read?
- You made 18 free throws out of 20 attempts. What’s your success rate?
(Answers: 20%, 40%, 90%)
🎉 Final Thoughts
Finding the percentage between two numbers is as easy as dividing, multiplying, and celebrating your math skills. Whether you’re calculating progress, savings, or scores, just remember:
Part ÷ Whole × 100 = Percentage
