Introduction

In mathematics, fractions and decimals are two ways to represent numbers. While fractions are often used to express proportions and ratios, decimals are used to represent numbers in a more familiar and intuitive way. In this article, we will focus on converting fractions to decimals, with a specific example of converting the fraction $$\frac{1}{5}$$ into a decimal.

What are Fractions and Decimals?

A fraction is a way to represent a part of a whole. It consists of two parts: a numerator (the top number) and a denominator (the bottom number). For example, the fraction $$\frac{1}{5}$$ represents one part out of five equal parts. On the other hand, a decimal is a way to represent a number using a point (.) as the separator between the whole number part and the fractional part. For example, the decimal 0.2 represents two tenths.

Why Convert Fractions to Decimals?

Converting fractions to decimals is an essential skill in mathematics, as it allows us to perform calculations and comparisons more easily. In many real-world applications, decimals are more convenient to work with than fractions. For example, in finance, interest rates are often expressed as decimals, while in science, measurements are often expressed as decimals.

Converting $$\frac{1}{5}$$ to a Decimal

To convert the fraction $$\frac{1}{5}$$ to a decimal, we can use the following steps:

Step 1: Divide the Numerator by the Denominator

To convert the fraction $$\frac{1}{5}$$ to a decimal, we need to divide the numerator (1) by the denominator (5).

Step 2: Perform the Division

Performing the division, we get:

\frac{1}{5} = 0.2

Therefore, the decimal equivalent of the fraction $$\frac{1}{5}$$ is 0.2.

How to Convert Fractions to Decimals in General

To convert a fraction to a decimal, we can use the following steps:

Step 1: Divide the Numerator by the Denominator

To convert a fraction to a decimal, we need to divide the numerator by the denominator.

Step 2: Perform the Division

Performing the division, we get the decimal equivalent of the fraction.

Tips and Tricks

Here are some tips and tricks to help you convert fractions to decimals:

Use a calculator: If you have a calculator, you can use it to divide the numerator by the denominator and get the decimal equivalent.
Simplify the fraction: Before converting the fraction to a decimal, simplify it by dividing both the numerator and the denominator by their greatest common divisor (GCD).
Use a conversion chart: If you need to convert a fraction to a decimal frequently, you can use a conversion chart to help you.
