With just a few simple calculations you have the right to convert 0.125 into a fraction and then placed it into its simplest form.

You are watching: What is 0.125 as a fraction

The simplest form of 0.125 together a portion is ⅛, yet just how would you do this calculation? Let’s take a look in ~ the procedures needed to transform 0.125 right into a fraction and then to placed that fraction into its easiest form.

The first part that converting any decimal into the simplest type of a fraction is to convert the decimal right into a fraction. Because that this very first conversion, any fraction will do, and knowing about the properties of fractions and decimals will assist you make these conversions. A conversion between decimals and fractions can be made very easily if you know the secret behind their connection to one another.


Converting A Decimal come A Fraction

Let’s take a rapid look at just how you can transform a decimal come a fraction. Constantly remember the decimals are simply parts the a totality number. This property way that just in its entirety numbers have actually columns, prefer tens and hundreds, the numbers that come after the decimal suggest also have actually columns, and these columns stand for what portion of a entirety number the decimal is. The very first column after ~ the decimal suggest is the tenths place, if the 2nd column is the percentage percent place, and so on.

So if one is provided the decimal 0.82, they understand that 0.82 isn’t a whole number, just 82% the a entirety number. The number 1 is tantamount to 100%, which way that converting a decimal to a percentage, and then to a fraction, is an extremely easy. Every you have to do is take the decimal in the percentage percent place and push it over to the right by two spaces, then placed the last column’s place value under the number. Because that example, 0.82 would come to be 82% or 82/100.

As another example, if you have the decimal 0.515, you can conveniently make this a fraction by noticing that the second five is in the thousandths place, which renders an indistinguishable to the portion 515/1000. Converting the decimal right into a fraction is done merely by counting the columns after the decimal point, climate pushing the decimal that countless spaces come the right. Finally, include the worth of the last column (in this case, this thousandths column) to the fraction as that is denominator.

Putting The fraction In most basic Form

Now that we have a portion – 515/100 – we can go around reducing the fraction, or placing it in its easiest form. 515/1000 is pretty messy, so exactly how would one go around finding the smallest, easiest version of the fraction? This deserve to be excellent by detect what is recognized as the Greatest typical Factor or Greatest typical Divisor (GCF or GCD), and also then using it to reduce a fraction to its most basic terms.


The greatest common factor is the largest, best number that you can divide evenly right into both the denominator and also numerator of the fraction. Let’s take the fraction 515/1000 and distill it come its most basic form. In this case, the greatest typical factor is 5. Dividing 5 right into 515 provides you 103/200.

Here’s a second example. If you have actually the decimal 0.875, you could convert it to a fraction (875/1000), and also then uncover the greatest common factor. In this case the GCF is 125, so separating 125 right into both the numerator and denominator will gain you ⅞.

In the two prior examples, we already knew what the GCF for the fountain was. However, you will do it usually have to do a little of math to determine the GCF the a fraction. There room multiple ways to find a fraction’s GCF, consisting of listing, prime factorization, and also the department method. Among the main ways to recognize the GCF that a portion is to make use of the element Factorization method. In the element factorization method, you will certainly multiply out the element factors usual to both numerator and denominator.

Finding The GCF

Let’s take it the fraction 18/24 for example. Prime determinants that deserve to only be multiply by one and also itself are prime factors, so with prime factorization, you’ll want to list out only the determinants which are prime numbers. In this case, the prime components of 18 are 2 and also 3. This are also the the smallest numbers which you can multiply together to get 18 (2 x 3 x 3 = 18). Meanwhile, the prime determinants of 24 are additionally 2 and also 3 (2 x 2 x 2 x 3 = 24). Multiply 2 and also 3 with each other gets you the number 6, i beg your pardon you deserve to then divide into 18/24 to obtain ¾.

It’s also feasible to uncover the greatest usual factor by simply listing out components of the 2 numbers till you run out of possible factors and find the GCF. As an example, if you were given the fraction 180/210 you could look for the GCF through listing out the factors like so:


Factors the 180 (other 보다 one): 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20 determinants of 210 (other 보다 one): 2, 3, 5, 6, 7, 10, 14, 15, 21

Let’s avoid here due to the fact that we may have actually the GCF already, or a way to uncover it. The usual factors between 180 and include, 2, 3, 5, 6, 10, and also 15. In this case, the greatest factor listed here is 15, and if we shot multiplying the by 2 we obtain 30, i m sorry is without doubt the greatest common factor because that the fraction.

Dividing 30 into 180/210 would gain you the fraction ⅞. Us could also have arrived on 30 because that the GCF through multiplying with each other the numbers 2, 3, and also 5. Another method to discover the GCF would have been just to store going and list out the factors until reaching 30, though as you deserve to see this procedure can take rather a little of time compared to element factorization.

One other means of recognize the GCF is the division Method. The department method involves separating the 2 numbers up right into smaller chunks till you have numbers that have the right to no longer be divided. Together an example, let’s try finding the GCF that 144/280 using the department method.

Dividing 144 and also 280 through 2 gives us: 72 and also 140.

72 and also 140 have much more common factors, so we have the right to attempt to division the number by two as soon as more.

Doing this will provide us: 36 and 70.

Once more, 36 and 70 tho have usual factors between the 2 numbers, so let’s division by 2 again to acquire 18 and 35. These 2 numbers don’t have any common determinants besides one, so let’s stop here and also see what we have.

Let’s multiply everything together: 2 x 2 x 2 = 8. Currently we have the right to divide 144/280 by 8 to obtain 18/35.

Now let’s use everything we’ve learned to convert 0.125 right into the simplest type of a fraction.

0.125 is simply 125/1000 once expressed together a fraction. Let’s divide 125/1000 through the greatest typical factor. The GCF in this circumstances is 5, and also dividing 125/1000 gets united state 25/200, which have the right to be separated once much more by 5 to obtain 5/40 and divided by 5 a last time to acquire ⅛.
