Introduction: Understanding Percentages

A percentage is a way of expressing a number as a fraction of 100. " So, 10% literally means 10 out of 100, or 10/100, which simplifies to 1/10. The symbol % represents "percent," meaning "per hundred.This fundamental understanding is key to calculating percentages accurately.

Method 1: The Decimal Method – Calculating 10% of 75.00

The most straightforward method involves converting the percentage to a decimal. To convert a percentage to a decimal, divide the percentage by 100. In our case:

10% ÷ 100 = 0.10

Now, multiply this decimal by the number you want to find the percentage of (75.00):

0.10 x 75.00 = 7.50

That's why, 10% of 75.00 is $\boxed{7.50}$.

Method 2: The Fraction Method – An Alternative Approach

As mentioned earlier, 10% is equivalent to the fraction 1/10. We can use this fraction to calculate 10% of 75.00:

(1/10) x 75.00 = 75.00 ÷ 10 = 7.50

This method confirms that 10% of 75.00 is indeed $\boxed{7.50}$.

Method 3: Using Proportions – A More Formal Approach

The concept of proportions offers a more formal and versatile approach to percentage calculations. A proportion is an equation stating that two ratios are equal. We can set up a proportion to solve for 10% of 75.

10/100 = x/75.00

Here, 'x' represents the unknown value (10% of 75.00). To solve for x, we cross-multiply:

10 x 75.00 = 100 x x

750 = 100x

x = 750 ÷ 100

x = 7.50

Again, this method confirms that 10% of 75.00 is $\boxed{7.50}$.

Understanding the Concept of Percentage Decrease and Increase

While our example focuses on finding a percentage of a number, understanding percentage increases and decreases is equally important. Because of that, 00 is discounted by 10%. Imagine a scenario where a product originally priced at 75.To calculate the discounted price, we first find the discount amount (which is 7.

75.00 - 7.50 = 67.50

The discounted price would be 67.50. Conversely, if the price increased by 10%, we would add the 7.50 to the original price.
