How to Take Out Percentage Marks: A Quick Guide

Understanding Percentages

A percentage is simply a way of expressing a number as a fraction of 100. The term "percent" comes from the Latin "per centum," meaning "by the hundred." When you see a percentage, like 25%, it means 25 out of every 100. So, to "take out" the percentage mark, you need to convert it back to its original fractional or decimal form.

Converting Percentages to Decimals

The most common way to take out the percentage mark is to convert the percentage to a decimal. Here's how:

1. Divide by 100: Divide the percentage number by 100.
2. Remove the % sign: The result is the decimal equivalent.

Example: Let's say you want to take out the percentage mark from 15%. 15 / 100 = 0.15. So, 15% is equal to 0.15.

Once you've converted the percentage to a decimal, you can use it in calculations just like any other decimal number. For example, if you want to find 15% of 200, you would multiply 200 by 0.15.

Converting Percentages to Fractions

Another way to take out the percentage mark is to express the percentage as a fraction. Here's how:

1. Write as a fraction with a denominator of 100: Use the percentage number as the numerator and 100 as the denominator.
2. Simplify the fraction: Reduce the fraction to its simplest form.

Example: Let's convert 40% to a fraction. 40/100 = 2/5. So, 40% is equal to the fraction 2/5.

Just like with decimals, you can use this fraction in calculations. If you need to calculate 40% of 50, you can multiply 50 by 2/5.

Common Percentage Problems and How to Solve Them

Here are some common scenarios where you might need to take out percentage marks:

• Finding a Percentage of a Number: What is 20% of 75? Convert 20% to 0.20, then multiply 0.20 * 75 = 15.
• Calculating Percentage Increase/Decrease: If a price increases from $50 to $60, find the percentage increase. The increase is $10. ($10 / $50) * 100 = 20%.
• Determining What Percentage One Number Is of Another: 30 is what percent of 150? (30 / 150) * 100 = 20%.

Tips for Using Percentages Effectively

• Double-check your work: Always verify your calculations to avoid errors.
• Understand the context: Pay attention to what the percentage refers to (e.g., percentage of a total, percentage change).
• Use decimals for calculations: When performing calculations, it’s usually easier to convert percentages to decimals.

Example Calculations

Let's explore some examples for calculating percentages:

• Example 1: Calculate the average percentage of marks in 6 subjects where a student scored: English 78, History 90, Geography 85, Economics 79, Political Science 88, and Sociology 75.

Solution: Total marks scored: 78 + 90 + 85 + 79 + 88 + 75 = 495 Maximum marks = 600 Percentage of marks = (495/600) x 100 = 82.5%

• Example 2: Calculate the percentage of marks for 6 subjects where student's scores are: Maths 85, Science 78, English 90, Social Science 82, Hindi 88, Computer Science 80.

Calculation: Total Marks Obtained = 85 + 78 + 90 + 82 + 88 + 80 = 503 Total Maximum Marks = 600 Percentage = 503/600 x 100 = 83.83%
