20 Percent Of 130

Unveiling the Mystery: Calculating 20% of 130

This article provides a comprehensive guide to calculating 20% of 130. Understanding percentages is a fundamental skill with applications across numerous fields, from everyday budgeting to complex financial analyses. We will explore multiple methods for solving this problem, illustrating each with clear examples and explanations, making the concept accessible to all levels of mathematical understanding.

Understanding Percentages

A percentage represents a fraction of 100. For example, 20% means 20 out of 100, or 20/100. This fraction can be simplified to 1/5. Therefore, calculating 20% of a number is equivalent to finding one-fifth of that number. In our case, we want to find 20% of 130, which means we need to determine what 20/100 (or 1/5) of 130 is.

Method 1: Converting Percentage to Decimal

The most straightforward method involves converting the percentage to its decimal equivalent. To do this, we divide the percentage by 100. So, 20% becomes 20/100 = 0.20.

Now, we simply multiply this decimal by the number we're interested in: 130.

0.20 x 130 = 26

Therefore, 20% of 130 is 26.

Example: Imagine a store offers a 20% discount on a $130 item. Using this method, we determine the discount amount to be $26. The final price after the discount would be $130 - $26 = $104.

Method 2: Using Fractions

As mentioned earlier, 20% is equivalent to the fraction 1/5. This method involves multiplying 130 by the fraction 1/5.

1/5 x 130 = 130/5

Now, we perform the division: 130 ÷ 5 = 26

This confirms that 20% of 130 is indeed 26.

Example: If you have 130 apples and you want to give away 20% (or one-fifth) of them, you would give away 26 apples.

Method 3: Proportion Method

The proportion method uses the concept of ratios to solve the problem. We can set up a proportion:

20/100 = x/130

Here, 'x' represents the unknown value (20% of 130). To solve for 'x', we cross-multiply:

20 130 = 100 x

2600 = 100x

Now, divide both sides by 100:

x = 2600/100 = 26

This method reinforces the concept that percentages represent a ratio.

Method 4: Using a Calculator

Modern calculators make percentage calculations incredibly easy. Most calculators have a percentage key (%). Simply enter 20%, press the multiplication key (), enter 130, and press the equals key (=). The calculator will directly provide the answer: 26. This is the quickest and most efficient method for everyday calculations.

Example: Checking your bank balance and calculating interest accrued on a $130 savings account earning 20% annual interest.

Summary

Calculating 20% of 130 can be achieved using several methods, each offering a unique approach to understanding the concept of percentages. Whether you utilize the decimal method, the fraction method, the proportion method, or a calculator, the answer remains consistent: 20% of 130 is 26. Choosing the method depends on personal preference, the complexity of the problem, and the tools available. Understanding these methods provides a solid foundation for tackling more complex percentage calculations in various contexts.
