Percentage — Lesson
🌟 Let's Discover the Magic of Percentages! 🌟
Imagine you are at a big fair in India 🎡. You want to buy a toy car that costs ₹100. The shopkeeper says, "Today, I will give you a 20% discount!" 🤩
What does 20% mean? How much money will you save? Let's find out!
1) What is Percentage? 🤔
Percentage means “out of 100”. The word “percent” comes from Latin and means “per hundred”.
So, 20% means 20 out of 100.
2) How to Understand Percentage with Examples?
| Example | Meaning | In Numbers |
|---|---|---|
| 50% | 50 out of 100 | 50/100 = 0.5 |
| 10% | 10 out of 100 | 10/100 = 0.1 |
| 5% | 5 out of 100 | 5/100 = 0.05 |
So, if you want to find 20% of ₹100, you do this:
20% of 100 = (20 ÷ 100) × 100 = 20
You save ₹20! So, you pay ₹80 for the toy car. 🎉
3) Key Formulas to Remember 🧮
Percentage (%) = (Part ÷ Whole) × 100
Part = (Percentage ÷ 100) × Whole
Whole = Part ÷ (Percentage ÷ 100)
4) Did You Know? 🤩
In India, the famous festival of Diwali often brings big sales with discounts shown in percentages! Stores might say, "Get 30% off!" This helps you save money while buying sweets 🍬 and gifts 🎁.
5) Exam Tips ✔️
- Always remember to divide by 100 when converting percentage to decimal.
- Check if the question asks for “percentage of” (find part), “what percentage” (find percentage), or “whole” (find total).
- Write your steps clearly. It helps you get marks even if the final answer is wrong.
- Practice questions like: “Find 25% of ₹200”, “What percent of 50 is 10?”, “If 30% of a number is 15, find the number.”
