## What is a Percentage?

Before we dive into the calculation, let’s first understand what a percentage is. A percentage is a way of expressing a number as a fraction of 100. For example, 50% is the same as 50/100 or 0.5.

## Calculating 20% of 800

Now, let’s get to the calculation of 20% of 800. To do this, we have to multiply 800 by 20% or 0.2. Here’s the formula:

20% of 800 = 800 x 0.2 = 160

So, 20% of 800 is 160.

## Why is this Calculation Important?

You may be wondering why this calculation is essential. Well, percentages are used in many areas of life, such as finance, business, and even in everyday activities like cooking. Understanding how to calculate percentages can help you make better financial decisions and manage your money more effectively.

## Common Percentage Calculations

Calculating percentages can seem daunting, but it’s essential to know some common calculations. Here are some examples:

– 10% of 500 = 50

– 25% of 200 = 50

– 50% of 1000 = 500

## Percentage Increase and Decrease

Another crucial aspect of percentages is calculating increase and decrease. For example, if a product’s price increases from $100 to $120, what is the percentage increase? To calculate this, we use the following formula:

Percentage increase = ((New value – Old value) / Old value) x 100

Using this formula, we can calculate the percentage increase as follows:

((120 – 100) / 100) x 100 = 20%

So, the percentage increase is 20%.

## Percentage Change in Stock Prices

Percentage change is also commonly used in the stock market to calculate gains and losses. For example, if a stock’s price increases from $50 to $60, what is the percentage increase? To calculate this, we use the following formula:

Percentage increase = ((New value – Old value) / Old value) x 100

Using this formula, we can calculate the percentage increase as follows:

((60 – 50) / 50) x 100 = 20%

So, the percentage increase is 20%.
