Imagine you and your friends are at a mango party in a sunny garden in India! There are 100 juicy mangoes. You ate 25 mangoes. How many mangoes did you eat in percentage? 🤔

📚 2) Core Concepts: What is a Percentage?
Percentage means "per hundred." It tells us how many parts out of 100. The symbol is %.
Example: If you ate 25 mangoes out of 100, you ate 25% of the mangoes! 🍽️
| Total Mangoes | Mangoes Eaten | Percentage Eaten |
|---|---|---|
| 100 | 25 | 25% |
You can also find percentage for any number using this method:
- Divide the part by the whole.
- Multiply by 100.
- Add the % sign.
Example: You have 50 laddus 🍬 and you eat 10. What % did you eat?
Calculation: (10 ÷ 50) × 100 = 20%
🔢 3) Key Formulas / Rules
Percentage (%) = (Part ÷ Whole) × 100
Part = (Percentage × Whole) ÷ 100
💡 4) Did You Know?
In India, the famous cricket player Sachin Tendulkar scored 100 centuries in international cricket! That means he scored 100 times 100 runs or more. If you think in percentages, he scored 100% many centuries! 🏏🎉
