## Understanding Percentages

Percentages are a fundamental concept in mathematics and everyday life. By expressing a portion or fraction of a whole, percentages allow us to easily compare and understand values. The word “percent” originates from the Latin term “per centum,” which translates to “per hundred.” In essence, one percent is equivalent to one hundredth or 1/100.

To **calculate percentages**, we use a simple formula: *(value/total value) x 100*. Here, the value represents the portion we are interested in, while the total value represents the entire quantity or set. By multiplying the fraction by 100, we convert it into a percentage. This **percentage formula** enables us to **calculate percentages** for various situations, ranging from finding percentages of numbers to determining **percentage change**.

“Percentages are like clues that help us decipher and compare different quantities in a simple and intuitive way.”

### Calculating Percentages Example

Let’s illustrate the **percentage formula** with an example. Suppose we want to find 30% of 200, where 30 is the value and 200 is the total value.

Value (30) | Total Value (200) | Percentage (%) |
---|---|---|

30 | 200 | ((30/200) x 100) = 15% |

Therefore, 30% of 200 is 15. This means that 30% represents a fraction of the total value, where that fraction is equal to 15% of the total.

**Understanding percentages** is essential not just for academic purposes, but also in real-life scenarios.

To increase a value by a certain percentage, multiply the value by (1 + percentage/100). For example, if you want to increase a value by 20%, you would multiply the value by 1.20. Let’s see it in action with an example:

Value: $100

Percentage: 20%

Increased value = $100 x (1 + 20/100) = $120

So, the value of $100 increased by 20% becomes $120.

### Percentage Decrease

To decrease a value by a certain percentage, multiply the value by (1 – percentage/100). For instance, if you want to decrease a value by 20%, you would multiply the value by 0.80. Let’s illustrate this with an example:

Value: $100

Percentage: 20%

Decreased value = $100 x (1 – 20/100) = $80

So, the value of $100 decreased by 20% becomes $80.

These formulas can be incredibly useful when determining discounts, calculating sale prices, or assessing tax rates. They provide a straightforward and efficient way to adjust values by a specific percentage, empowering you to make accurate calculations quickly.

Value | Percentage | Increased Value | Decreased Value |
---|---|---|---|
