What is a Percentage?
A percentage is a way to express a part of something in terms of 100. It’s like breaking down a whole into smaller, more manageable pieces. Imagine you have a pizza, and you want to know how much you’ve eaten. If you’ve devoured three out of eight slices, that’s your percentage!

Our mission is simple: by the end of this adventure, you’ll not only grasp what percentages are but also be able to use them like a math wizard in everyday situations.
Understanding the Percent Symbol: %
First things first, let’s decode the symbol – %. When you see this little guy, it means “per hundred.” So, 25% is the same as saying 25 per hundred or 25 out of 100.
Visualizing Percentages: The Pizza Analogy
Let’s return to our pizza adventure. If you’ve eaten 50% of the pizza, you’ve consumed half of it. Visualizing percentages in terms of familiar objects, like pizzas or chocolate bars, can make the concept more relatable and fun.
Converting Percentages to Decimals and Fractions
Here’s a nifty trick: a percentage is essentially a fraction with a denominator of 100. So, 25% is the same as 25/100, which can also be written as 0.25 when expressed as a decimal. Understanding these conversions makes working with percentages a breeze!
Finding Percentages: The Easy Formula
Let’s say you want to find out what 20% of 80 is. The formula is your secret weapon: Percentage × Whole = Part. In this case, 20% of 80 is 0.2 × 80, which equals 16. Voila! You’ve found your answer.
Percentage Increase and Decrease: The Rollercoaster Ride
Imagine your favorite ice cream goes on sale, and the price drops by 30%. That’s a percentage decrease. On the flip side, if it gets more expensive by 50%, that’s a percentage increase. Understanding these changes helps you navigate the twists and turns of percentages.
