Introduction

When working with fractions and percentages, it's essential to understand how to convert between the two. In this article, we'll explore how to write a fraction as a percentage. We'll use the example of the fraction $\frac{4}{5}$ to demonstrate the process.

What is a Percentage?

A percentage is a way to express a value as a fraction of 100. It's denoted by the percent sign (%) and is often used to represent a proportion or a ratio. For example, 25% is equivalent to $\frac{25}{100}$ .

Converting a Fraction to a Percentage

To convert a fraction to a percentage, we need to divide the numerator by the denominator and multiply by 100. This will give us the percentage equivalent of the fraction.

Example: Converting $\frac{4}{5}$ to a Percentage

Let's use the example of the fraction $\frac{4}{5}$ to demonstrate the process.

$\frac{4}{5}$ can be converted to a percentage by dividing the numerator (4) by the denominator (5) and multiplying by 100.

$\frac{4}{5} \times 100 = \frac{400}{5} = 80\%$

Therefore, $\frac{4}{5}$ is equivalent to 80%.
