With simply a few simple calculations you can convert 0.125 into a fraction and then placed it into its simplest form.

You are watching: Whats .125 as a fraction

The simplest form of 0.125 as a portion is ⅛, yet just how would you carry out this calculation? Let’s take it a look at the procedures needed to transform 0.125 right into a fraction and climate to placed that portion into its simplest form.

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


Converting A Decimal come A Fraction

Let’s take a fast look at exactly how you can convert a decimal come a fraction. Constantly remember the decimals are simply parts the a whole number. This property way that just overall numbers have columns, favor tens and hundreds, the numbers that come after ~ the decimal point also have columns, and also these columns represent what section of a totality number the decimal is. The very first column ~ the decimal allude is the one per 10 place, while the second column is the percentage percent place, and also so on.

So if one is offered the decimal 0.82, they recognize that 0.82 no a entirety number, simply 82% the a whole number. The number 1 is tantamount to 100%, which means that converting a decimal to a percentage, and then come a fraction, is very easy. All you need to do is take the decimal in the percentage percent place and push it end to the appropriate by 2 spaces, then put the last column’s place value under the number. For example, 0.82 would become 82% or 82/100.

As an additional example, if you have actually the decimal 0.515, girlfriend can quickly make this a fraction by noticing that the 2nd five is in the thousandths place, which provides an equivalent to the portion 515/1000. Convert the decimal right into a fraction is done just by count the columns after the decimal point, climate pushing the decimal that plenty of spaces come the right. Finally, include the value of the last column (in this case, this thousandths column) to the fraction as that is denominator.

Putting The fraction In easiest 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 quite messy, so how would one go about finding the smallest, easiest version of the fraction? This have the right to be done by finding what is known as the Greatest usual Factor or Greatest typical Divisor (GCF or GCD), and also then using it to reduce a fraction to its most basic terms.


The greatest typical factor is the largest, biggest number that you have the right to divide evenly into both the denominator and also numerator the the fraction. Let’s take it the fraction 515/1000 and distill it to its most basic form. In this case, the greatest usual factor is 5. Separating 5 right into 515 gives you 103/200.

Here’s a second example. If you have the decimal 0.875, you could transform it come a fraction (875/1000), and then discover the greatest common factor. In this instance the GCF is 125, so dividing 125 right into both the numerator and denominator will acquire you ⅞.

In the two prior examples, we already knew what the GCF because that the fractions was. However, you’ll usually need to do a bit of math to recognize the GCF that a fraction. There space multiple ways to discover a fraction’s GCF, including listing, element factorization, and the division method. One of the key ways to recognize the GCF the a portion is to use the prime Factorization method. In the element factorization method, you will multiply the end the prime factors common to both numerator and denominator.

Finding The GCF

Let’s take the fraction 18/24 for example. Prime components that have the right to only be multiplied by one and itself room prime factors, so through prime factorization, you’ll desire to list out just the components which space prime numbers. In this case, the prime determinants of 18 are 2 and also 3. This are also the smallest numbers i beg your pardon you could multiply with each other to get 18 (2 x 3 x 3 = 18). Meanwhile, the prime components of 24 are likewise 2 and 3 (2 x 2 x 2 x 3 = 24). Multiplying 2 and 3 with each other gets girlfriend the number 6, i beg your pardon you have the right to then divide right into 18/24 to gain ¾.

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


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

Let’s prevent here because we may have the GCF already, or a way to find it. The typical factors in between 180 and also include, 2, 3, 5, 6, 10, and 15. In this case, the greatest factor listed here is 15, and also if we shot multiplying the by 2 we obtain 30, i beg your pardon is certainly the greatest common factor because that the fraction.

Dividing 30 into 180/210 would get you the portion ⅞. We could also have arrived on 30 because that the GCF by multiplying with each other the numbers 2, 3, and 5. Another means to uncover the GCF would have actually been simply to save going and list out the components until getting to 30, though together you can see this process can take fairly a bit of time contrasted to prime factorization.

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

Dividing 144 and 280 by 2 provides us: 72 and also 140.

72 and 140 have much more common factors, so we deserve to attempt to division the number by two once more.

Doing this will provide us: 36 and 70.

Once more, 36 and also 70 quiet have common factors in between the 2 numbers, therefore let’s divide by 2 again to acquire 18 and 35. These 2 numbers don’t have any common determinants besides one, so let’s prevent here and also see what us have.

Let’s multiply whatever together: 2 x 2 x 2 = 8. Now we deserve to divide 144/280 by 8 to get 18/35.

Now let’s apply everything we’ve learned to converting 0.125 right into the simplest kind of a fraction.

0.125 is just 125/1000 as soon as expressed as a fraction. Let’s division 125/1000 by the greatest common factor. The GCF in this circumstances is 5, and dividing 125/1000 gets us 25/200, which have the right to be separated once much more by 5 to obtain 5/40 and divided through 5 a last time to acquire ⅛.
