# What Is 18% Of 72?

## Introduction

Calculating percentages is a fundamental aspect of mathematics that we use in our daily lives. Whether you are shopping, calculating your taxes, or interpreting statistics, knowing how to calculate percentages is important. In this article, we will take a closer look at the percentage 18% of 72.

## What does percentage mean?

A percentage is a way of expressing a value as a fraction of 100. It is a way of representing a proportion or part of a whole. For example, if you say that you scored 80% on a test, it means that you got 80 out of 100 marks.

## How to calculate percentages

To calculate a percentage, you need to divide the part by the whole and multiply by 100. The formula can be expressed as:

Percentage = (Part / Whole) × 100

## Calculating 18% of 72

Now, let’s calculate 18% of 72 using the formula we just learned. We know that:

Part = 18

Whole = 72

Percentage = (18 / 72) × 100

Percentage = 0.25 × 100

Percentage = 25

## What does 18% of 72 mean?

So, 18% of 72 means that 18% of 72 is 25. In other words, if you have 72 items and you want to find out what 18% of them is, the answer is 25.

## How to use percentages in real life

Now that we know how to calculate percentages, let’s look at some examples of how we can use them in real life:

### 1. Shopping

Suppose you see a shirt that costs \$40, and it is on sale for 30% off. To find out the sale price, you can use the formula:

Sale price = Original price – (Discount % × Original price)

Sale price = \$40 – (30% × \$40)

Sale price = \$28

### 2. Taxes

When you pay your taxes, you need to know your income tax rate. Suppose your income tax rate is 20%, and your income is \$50,000. To find out how much tax you need to pay, you can use the formula:

Tax amount = Income × Tax rate

Tax amount = \$50,000 × 20%

Tax amount = \$10,000

### 3. Statistics

Percentages are often used in statistics to show the relative frequency of an event. For example, if 60 out of 100 people prefer coffee over tea, the percentage of people who prefer coffee is:

Percentage = (60 / 100) × 100

Percentage = 60%

## Conclusion

Calculating percentages is an important skill that we use in many areas of our lives. In this article, we learned how to calculate 18% of 72 and saw some examples of how we can use percentages in real life. I hope this article has been helpful to you!
