Ever wondered how to calculate percentages? Figuring out what percentage 12 is of 30 is a common task, whether you're calculating grades, discounts, or even just understanding data. Let's break down this calculation and explore how to solve similar problems.

Understanding Percentages

A percentage represents a part of a whole, expressed as a fraction of 100. So, 12 out of 30 is essentially asking "what fraction of 30 is 12, expressed as a fraction of 100?"

The Formula:

The basic formula for calculating percentages is:

(Part / Whole) * 100 = Percentage

In our case:

• Part: 12
• Whole: 30

Calculation:

1. Divide the part by the whole: 12 / 30 = 0.4
2. Multiply the result by 100: 0.4 * 100 = 40

Answer:

Therefore, 12 is 40% of 30.

• Grades: If you get 12 questions right out of 30 on a test, your score is 40%.
• Data Analysis: If 12 out of 30 people surveyed prefer a particular brand of coffee, that represents 40% of the respondents.
