How to do / calculate % percentages for beginners?
Introduction to Percentages:
Imagine you have a whole pie, and you want to share it with your friends. Percentages are like a way to describe how much of that pie each person gets.
What's a Percentage?
A percentage is a number out of 100. It's like saying "this is how much out of every 100." For example, if you say you got 80% on a test, it means you got 80 marks out of 100.
Converting Percentages:
To work with percentages, you sometimes need to turn them into decimals. To do that, you divide the percentage by 100. For example, if you have 40%, you divide 40 by 100 to get 0.40 as a decimal.
Practical Examples:
Let's look at some everyday situations where percentages are used:
Discounts while Shopping: Imagine you're buying a toy that costs $100, but it's on sale for 30% off. To find how much you'll save, calculate 30% of $100: 0.30 × $100 = $30. So, you'll save $30 and pay only $70.
Calculating Tips: When you eat at a restaurant, it's customary to leave a tip for the server. If the bill is $50 and you want to leave a 15% tip, calculate 15% of $50: 0.15 × $50 = $7.50. So, you'd leave a $7.50 tip.
Understanding Test Scores: If you scored 75 marks out of 100 on a test, your score is 75%. This tells you that you got 75 marks out of every 100 possible.
