Converting Decimal to Fraction: 0.8 in Fraction Form

In mathematics, decimals and fractions are two different ways to represent numbers. While decimals use a point to separate the whole part from the fractional part, fractions use a line or a slash to separate the numerator from the denominator. Converting decimals to fractions can be a straightforward process, and in this article, we will explore how to convert 0.8 into a fraction.

Understanding Decimals and Fractions

Before we dive into the conversion process, let's quickly review what decimals and fractions are.

• Decimals are a way to represent numbers using a point to separate the whole part from the fractional part. For example, 0.8 is a decimal number.
• Fractions, on the other hand, represent numbers using a line or a slash to separate the numerator from the denominator. For example, 4/5 is a fraction.

Converting 0.8 to a Fraction

To convert 0.8 to a fraction, we can use the following steps:

1. Write the decimal number as a fraction by placing the decimal part over the place value of the last digit.
2. Simplify the fraction by dividing the numerator and denominator by the greatest common divisor (GCD).

Using these steps, we can convert 0.8 to a fraction as follows:

0.8 = 8/10

Simplifying the Fraction

To simplify the fraction, we need to find the greatest common divisor (GCD) of 8 and 10. The GCD of 8 and 10 is 2. Therefore, we can divide the numerator and denominator by 2 to simplify the fraction:

8 ÷ 2 = 4 10 ÷ 2 = 5

So, the simplified fraction is:

4/5
