About Percentage

Do you know that the word "percentage" comes from a cool ancient language called Latin? The Latin word "Percentum" means "per hundred." It's like a secret code that helps us understand how much of something we have.

A percentage is a special number that tells you how many parts you have out of 100. It's like a magical way of dividing things into equal pieces. It's a way to tell you how much of a whole thing you have and it’s usually shown with the symbol "%".

How to Find Percentage?

Imagine you have a jar filled with colorful marbles. You want to show your friends how many marbles you have compared to the total number of marbles in the jar. That's where percentages come in!

If you have 25 marbles, you can say you have 25% of the marbles in the jar. That means you have a quarter of the total marbles! You can write it as "25%." The symbol "%" looks like a tiny magic wand that represents a percentage.

How to Calculate Percentage?

Finding percentages is like using a special formula to solve a math puzzle. It's a simple step-by-step process that helps us figure out how much of something we have. Let's dive into the formula:

Step 1: Start with the whole thing

Imagine you have a basket full of juicy apples. This basket represents the whole, and we'll call it "W" for the whole.

Step 2: Identify the part you want to find
Let's say you want to know how many apples you have compared to the whole basket. We'll call this part "P" for the part.
Step 3: the percentage formula

It goes like this: P divided by W, and then multiply the result by 100. That is: Percentage = P (part of apples) / W (whole apples) * 100%

The percentage formula is like a treasure map that leads us to the answer. It helps us understand proportions and compare a part to the whole. It's a super useful tool for solving math problems and exploring the world of numbers!

Use : Percentage of Marks

Percentage is a helpful way of comparing quantities, and it's easier to understand than fractions. Let's use a fun example to see why percentages are preferred.

Imagine Yusra and Tasnim are talking about their math scores.Yusra proudly says, "I scored 80 marks in math!" Tasnim responds, "Well, I got 70 marks in math." But wait, can we decide who did better based on these numbers? Not yet!To know the truth, we need to know the total marks available. So, here's what we find out:
Yusra's total marks were 120, while Tasnim's total marks were 100. Ah, now we have more information!Now, let's calculate the percentage to see who really did better. We use the following formula: (Marks obtained ÷ Total marks) x 100.For Yusra, it's (80 ÷ 120) x 100 = 66.67%. And for Tasnim, it's (70 ÷ 100) x 100 = 70%.
So, we can see that Tasnim scored 70% while Yusra scored 66.67%. That means Tasnim did a bit better in math!

Conclusion

Percentages help us compare scores accurately because they consider the total marks available. It's like looking at the big picture instead of just a small part.Using percentages, we can make fair comparisons and understand who performed better in different situations. It's a super handy tool for understanding proportions and evaluating performances!
