Step-by-Step Calculation

To calculate 64% of 25, follow these simple steps:

Convert the percentage to a decimal: Divide 64 by 100 to get 0.64.
Multiply the decimal by the number: Multiply 0.64 by 25.
Perform the multiplication: 0.64 x 25 = 16.

So, 64% of 25 equals 16. This means that if you have a total of 25 items and you take 64% of them, you will have 16 items.

Real Examples

Let's look at some practical examples to see how this calculation applies in real life:

Shopping Discount: Imagine you're buying a $25 item that is on sale for 64% off. The discount amount is 64% of 25, which is $16. So, you would pay $25 - $16 = $9 for the item.
Academic Grading: If a test is out of 25 points and you score 64%, you would have earned 16 points.
Nutrition Facts: If a food label says a serving contains 64% of the daily recommended intake of a nutrient, and the daily value is based on 25 grams, then one serving provides 16 grams of that nutrient.

These examples show how understanding percentages can help you make sense of numbers in everyday situations.

Scientific or Theoretical Perspective

From a mathematical standpoint, percentages are a way to express proportions. The formula for finding a percentage of a number is:

$ \text{Percentage of a number} = \left( \frac{\text{Percentage}}{100} \right) \times \text{Number} $

In our case:

$ 64% \text{ of } 25 = \left( \frac{64}{100} \right) \times 25 = 0.64 \times 25 = 16 $

This formula is foundational in many fields, including statistics, economics, and science, where data is often presented as percentages for easier comparison and understanding.

Common Mistakes or Misunderstandings

A common mistake when dealing with percentages is confusing the percentage with the actual number. For example, some might mistakenly think that 64 of 25 means 64 divided by 25, which would give a different result (approximately 2.56). However, "64 of 25" specifically refers to 64% of 25, not a division problem.

Another misunderstanding is forgetting to convert the percentage to a decimal before multiplying. Always remember to divide the percentage by 100 first to get the correct decimal form.
