What is -0.73 as a fraction?

In this article, we will guide you step by step through the process of converting the decimal -0.73 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 -0.73 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.

-0.73 as a fraction equals -73/100 or 73/-100

Now let's break down the steps for converting -0.73 into a fraction.

Step 1:

First, we express -0.73 as a fraction by placing it over 1:
-0.73/1

Step 2:

Next, we multiply both the numerator and denominator by 10 for each digit after the decimal point.
-0.73 x 100/1 x 100
  =  
-73/100

Step 3:

Next, we find the Greatest Common Factor (GCF) for -73 and 100. Keep in mind a factor is just a number that divides into another number without any remainder.
The factors of -73 are:
The factors of 100 are: 1 2 4 5 10 20 25 50 100
The GCF of -73 and 100 is: -1

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 -1 in this case.
-73 ÷ -1/100 ÷ -1
  =  
73/-100


Great Work! We've just determined that -0.73 as a fraction equals -73/100 or 73/-100 in its simplest form.
