Are you looking to convert a fraction to a decimal number? We can guide you step-by-step on how to calculate and show exactly what the fractional form of 2.1 is. So, if you are in the right place, let’s go ahead and show you how to convert 2.1 to a fraction.
There are many reasons why you might want to convert a fraction to a decimal, but the most common reason is that your teacher told you to compare two fractions quickly and easily.
Before we begin here, let’s quickly recap fractions. It’s important to double check your work when dealing with fractions, as it can be easy to make mistakes. If you have already done a lot of work with fractions, you probably already know that the number below the fraction line is called the denominator, and the number above the fraction line is called the numerator.
Okay, the first thing to do here is to show that any number can be a fraction if you take the denominator as 1.
In this case, we have to count the numbers after the decimal point. To achieve this, we need to get rid of the decimal places completely, which means we really want to do what with our fraction, a whole number in the numerator.
The concept is as follows: if there are 10,000 and three numbers, and if there are 1,000 and two numbers, then after the decimal point, there are numbers one if, we need to multiply both the numerator and the denominator by 10 to obtain a whole fraction.
In our situation, where 1 is a single-digit number, we must multiply both the numerator and denominator by 10.
Now we simply have to perform that multiplication in order to obtain our complete fraction:
The next step is to simplify this fraction, as we also sometimes need to find the greatest common factor.
The GCF can be a bit complicated to figure out by hand, but you can use a calculator to make it handy.
In the case of 10 and 21, we can simplify the fraction by dividing both the numerator and the denominator by their greatest common divisor, which is 1. This means we can simplify the fraction by dividing both the numerator and the denominator by 1.
Here is the full response for your pleasure. We have determined the fractional representation of 2.1 through a quick and concise process. Voila!
2 1/10.
Note: since 21 is larger than 10, we have further simplified this fraction to a mixed number.
Now you can go back and forth as much as your heart desires to convert fractions to decimals. Hopefully, this tutorial has helped you understand how to convert a fraction into a decimal number.
