What Is 8 Of 120

What is 8% of 120? A thorough look to Percentage Calculations

Understanding percentages is a fundamental skill in many areas of life, from calculating discounts in a shop to understanding financial reports. In practice, we'll even touch upon real-world applications to solidify your understanding. On the flip side, this article will break down how to calculate 8% of 120, providing not just the answer but also a thorough explanation of the process, different methods for solving the problem, and exploring the broader context of percentage calculations. Let's dive in!

Understanding Percentages

Before we tackle the specific problem of finding 8% of 120, let's refresh our understanding of what percentages represent. A percentage is a fraction expressed as a number out of 100. The symbol "%" represents "per hundred" or "out of 100". So for instance, 50% means 50 out of 100, which is equivalent to ½ or 0. 5 as a decimal.

Percentages are used to express proportions or ratios relative to a whole. They are incredibly versatile and used extensively across various fields, including:

• Finance: Calculating interest rates, taxes, discounts, and profit margins.
• Science: Representing experimental results, statistical data, and compositional analysis.
• Everyday Life: Understanding sales, tips, and even nutritional information on food labels.

Method 1: Using the Decimal Equivalent

This is the most straightforward method to calculate 8% of 120. The first step is to convert the percentage to its decimal equivalent. To do this, we divide the percentage by 100:

8% ÷ 100 = 0.08

Now, we simply multiply the decimal equivalent by the number we're finding the percentage of:

0.08 x 120 = 9.6

Which means, 8% of 120 is 9.6.

Method 2: Using Fractions

Percentages can also be expressed as fractions. Since 8% means 8 out of 100, we can write it as the fraction ⁸⁄₁₀₀. To find 8% of 120, we multiply 120 by this fraction:

(⁸⁄₁₀₀) x 120 = (8 x 120) / 100 = 960 / 100 = 9.6

This method confirms our previous result: 8% of 120 is 9.6.

Method 3: Proportion Method

This method uses the concept of proportion to solve the problem. We can set up a proportion where we have:

x/120 = 8/100

Here, 'x' represents the unknown value (8% of 120). To solve for 'x', we can cross-multiply:

100x = 8 x 120

100x = 960

x = 960 / 100

x = 9.6

Again, this method yields the same answer: 8% of 120 is 9.6.

Understanding the Result

The result, 9.Practically speaking, 6 apples. Which means 6, represents a portion of 120. Imagine you have 120 apples, and you want to give away 8% of them. Worth adding: you would give away 9. In real-world scenarios, you would likely round this down to 9 apples if you couldn't give away fractions of an apple.

Real-World Applications

Let's explore some practical applications to illustrate the relevance of percentage calculations:

• Sales Tax: If you buy an item for $120 and the sales tax is 8%, you would pay an additional $9.60 in tax. The total cost would be $120 + $9.60 = $129.60.

• Discounts: If a store offers an 8% discount on a $120 item, you would save $9.60. The final price would be $120 - $9.60 = $110.40.

• Commission: If a salesperson earns an 8% commission on sales, and they sell $120 worth of goods, they would earn $9.60 in commission.

• Interest: If you invest $120 and earn 8% interest, you would earn $9.60 in interest.

Beyond the Basics: Calculating Other Percentages

Now that we've mastered calculating 8% of 120, let's briefly discuss how to tackle other percentage calculations:

Finding x% of y:

The general formula for finding x% of y is:

(x/100) * y

Replace 'x' with the percentage you want to calculate and 'y' with the number you're finding the percentage of.

Finding what percentage x is of y:

To find what percentage x is of y, use the formula:

(x/y) * 100

Finding a number given a percentage and a part:

If you know a percentage and the resulting value, you can find the original number. To give you an idea, if 8% of a number is 9.6, the original number is found by:

9.6 / (8/100) = 120
