### What is a Percentage?

A percentage is a way of representing numbers in terms of their relation to 100

A percentage can be calculated by dividing the number by 100 then multiplying this number by 100.

### Building Your Understanding of Percentages

Understanding percentages can be difficult, but it's important for the sake of making the right decisions.

One way to make learning math easier is to understand percentages. Percentages are just fractions with an additional digit tacked on.

A percentage can be written as a fraction, decimal, or percent sign. The fraction 0.5 is equal to 50%, but if you want to express that number as a percent you write it as 50%.

Formula:

Percentage = [(Whole number) ÷ (100)] * 100

Example:

If I had 1 apple out of 100, what would be my percentage?

The answer is 1%.

### How to Calculate a Percentage Using a Calculator or Without One

A percent is a ratio that compares the number of items in a group to the total number of items. It can be expressed as a number or as a fraction, and it is always less than one. To calculate a percentage, multiply the part by 100 and divide by the whole.

Examples:

Problem: What is 75% as a decimal?

Solution: 75% = .75

Problem: What is 100% as a decimal?

Solution: 100%= 1

### Percentages in Everyday Life and Business Situations - Examples and Explanations

Percentages are a very common way to express a smaller number as a proportion of a larger one. Percentages can be expressed mathematically as a ratio of 100 (or some other value). For example, 45% is the same as 45/100 which is expressed in decimal form as 0.45.

For some purposes, it has been found useful to express percent values in a fraction of 100; for example, instead of writing "a fraction 3/10", it would be more customary to write "30%".

Many people use percentages daily without realizing it. They are used for makeup calculations, sales tax, and discounts.

### Why Should You Start Learning About Percentages?

Percentages are a vital part of everyday life as they are used as a measurement for everything from checking out at the grocery store, to determining how much interest you'll pay on a loan. Learning the basics of percentages is important because it is a part of many day-to-day life skills that even the most mathematically challenged person will use.

It is not just numbers that percentages represent it is also relationships between numbers. For example, knowing about percentage change allows you to answer questions such as "What will be my monthly payment if I take out a loan?" or "If I increase my price by 10% what will happen to my sales?" This knowledge will allow you to make better decisions.

Percentages, and percentage changes, are used in the real world to understand the significance of a change. Understanding how percentages work will help you better understand your financial situation, what you need to do to improve it, and how much that might cost.
