Finding a percentage of a number is a common calculation used in many everyday situations, from calculating sales tax to determining discounts. This article will clearly explain how to calculate 10% of 115, and then offer some helpful tips and real-world examples.

Understanding Percentages

Before we dive into the calculation, let's quickly review what percentages represent. A percentage is a fraction of 100. For example, 10% means 10 out of 100, or 10/100, which simplifies to 1/10.

Calculating 10% of 115: Two Methods

There are two straightforward methods to calculate 10% of 115:

Method 1: Using the Decimal Equivalent

The easiest way is to convert the percentage to its decimal equivalent. Since 10% is equal to 0.10 (or simply 0.1), we can multiply 115 by 0.1:

115 x 0.1 = 11.5

Therefore, 10% of 115 is $\boxed{11.5}$

Method 2: Finding One-Tenth

10% is equivalent to one-tenth (1/10). To find one-tenth of a number, you simply divide the number by 10.

115 ÷ 10 = 11.5

This also shows that 10% of 115 is $\boxed{11.5}$

Real-World Applications

Understanding percentage calculations is crucial for various real-world applications. Here are a few examples:

• Sales Tax: If you buy something for $115 and the sales tax is 10%, you'll pay an additional $11.50 in tax.
• Discounts: A 10% discount on a $115 item would mean a savings of $11.50. Your final cost would be $103.50 ($115 - $11.50).
• Tips: Calculating a 10% tip on a $115 restaurant bill would be $11.50.
• Commission: If a salesperson earns a 10% commission on sales, a $115 sale would earn them $11.50.

Calculating Other Percentages of 115

Using the same principles, you can easily calculate other percentages of 115. For example:

• 20% of 115: (115 x 0.2) = 23
• 5% of 115: (115 x 0.05) = 5.75
• 15% of 115: (115 x 0.15) = 17.25

By understanding these basic percentage calculations, you can confidently tackle various mathematical problems in everyday life and beyond. Remember, practice makes perfect!
