What is the Percentage of 24 out of 30? A Simple Guide to Percentage Calculations

Finding the percentage of 24 out of 30 is a common math problem. Whether you're calculating grades, sales figures, or anything in between, knowing how to solve this type of problem is essential. This article will show you the simple steps involved, plus offer some helpful tips and examples.

Understanding Percentages

Before we dive into the calculation, let's quickly review what a percentage represents. A percentage is a fraction out of 100. For example, 50% means 50 out of 100, or 50/100, which simplifies to 1/2.

Calculating the Percentage: Step-by-Step

Here's how to calculate the percentage of 24 out of 30:

1. Set up a fraction: Write the problem as a fraction: 24/30. This represents 24 parts out of a total of 30 parts.

2. Convert the fraction to a decimal: Divide the numerator (24) by the denominator (30): 24 ÷ 30 = 0.8

3. Convert the decimal to a percentage: Multiply the decimal by 100%: 0.8 x 100% = 80%

Therefore, 24 out of 30 is 80%.

Alternative Method: Using Proportions

You can also solve this using a proportion:

Let 'x' represent the percentage:

24/30 = x/100

To solve for x, cross-multiply:

30x = 2400

x = 2400/30

x = 80

Therefore, x = 80%, confirming our previous calculation.

Practical Applications

Understanding percentage calculations is incredibly useful in everyday life. Here are some examples:

• Grading: If you answered 24 out of 30 questions correctly on a test, you scored 80%.

• Sales: If a store offers a 20% discount on an item originally priced at $30, the discount is $6 (20% of $30). The sale price is $24.

• Statistics: Percentages are frequently used to represent data in charts and graphs, making it easier to understand complex information.

Key Takeaways

• To find a percentage, express the given numbers as a fraction, convert it to a decimal, and then multiply by 100%.
• The proportion method provides an alternative way to solve for the percentage.
• Mastering percentage calculations is vital for various aspects of daily life and academic/professional settings.
