What is .80 as a fraction?

In this article, we will guide you step by step through the process of converting the decimal .80 into a fraction. We will start by understanding how a decimal represents the fractional part of a number, then break down the steps to rewrite .80 as a fraction. Finally, we will simplify the fraction by identifying and applying the Greatest Common Factor, ensuring the results are in the simplest form.

By the end of this guide, you should have a good understanding of decimal to fraction conversions and be able to apply this knowledge to various mathematical problems. Let's begin.

.80 as a fraction equals 80/100 or 4/5

Now let's break down the steps for converting .80 into a fraction.

Step 1:

First, we express .80 as a fraction by placing it over 1:.80/1

Step 2:

Next, we multiply both the numerator and denominator by 10 for each digit after the decimal point..80 x 100/1 x 100  =  80/100

Step 3:

Next, we find the Greatest Common Factor (GCF) for 80 and 100. Keep in mind a factor is just a number that divides into another number without any remainder.The factors of 80 are: 1 2 4 5 8 10 16 20 40 80The factors of 100 are: 1 2 4 5 10 20 25 50 100The GCF of 80 and 100 is: 20

Step 4:

To simplify the fraction, we divide both the numerator and denominator by their greatest common factor (GCF), which we calculated in the previous step. The GCF value is 20 in this case.80 ÷ 20/100 ÷ 20  =  4/5Great Work! We've just determined that .80 as a fraction equals 80/100 or 4/5 in its simplest form.
