Understanding the fractional form of 0.8 can seem daunting, but it's actually quite simple. In this article, we'll break down the process step by step, using practical examples and clear explanations. By the end of this article, you'll be able to convert 0.8 to a fraction with ease.
What is a Fraction?
Before diving into the fractional form of 0.8, let's quickly review what a fraction is. A fraction is a way to represent a part of a whole. It consists of two parts: the numerator (the top number) and the denominator (the bottom number). The numerator tells us how many equal parts we have, while the denominator tells us how many parts the whole is divided into.
For example, the fraction 3/4 represents three equal parts out of a total of four parts.
Converting 0.8 to a Fraction
Now, let's convert 0.8 to a fraction. To do this, we need to find the numerator and denominator.
Since 0.8 is a decimal number, we can think of it as 8 tenths. The numerator is 8, and the denominator is 10 (since there are 10 tenths in a whole).
Step 1: Write the Decimal as a Fraction
So, we can write 0.8 as a fraction: 8/10.
Step 2: Simplify the Fraction
However, the fraction 8/10 can be simplified. We can divide both the numerator and denominator by 2, resulting in the simplified fraction: 4/5.
Why is the Fractional Form of 0.8 Important?
