With simply a couple of simple calculations you deserve to convert 0.125 right into a fraction and then placed it right into its simplest form.

You are watching: What is .0125 as a fraction

The simplest type of 0.125 together a fraction is ⅛, yet just how would you carry out this calculation? Let’s take it a look in ~ the procedures needed to convert 0.125 right into a fraction and then to put that fraction into its simplest form.

The very first part of converting any kind of decimal right into the simplest form of a fraction is to transform the decimal into a fraction. Because that this an initial conversion, any fraction will do, and knowing around the properties of fractions and decimals will aid you do these conversions. A conversion in between decimals and fractions can be made very easily if you know the mystery behind their relationship to one another.


Converting A Decimal come A Fraction

Let’s take it a rapid look at just how you can convert a decimal come a fraction. Always remember that decimals are simply parts that a entirety number. This property means that just all at once numbers have columns, favor tens and hundreds, the numbers that come after the decimal point also have columns, and these columns stand for what section of a entirety number the decimal is. The first column ~ the decimal allude is the tenths place, while the 2nd column is the hundredths place, and also so on.

So if one is given the decimal 0.82, they recognize that 0.82 no a whole number, just 82% of a whole number. The number 1 is indistinguishable to 100%, which way that convert a decimal to a percentage, and then come a fraction, is really easy. Every you have to do is take the decimal in the hundredths place and push it end to the appropriate by 2 spaces, then placed the critical column’s ar value under the number. For example, 0.82 would come to be 82% or 82/100.

As another example, if you have actually the decimal 0.515, you can easily make this a portion by noticing the the 2nd five is in the thousandths place, which makes an indistinguishable to the portion 515/1000. Convert the decimal into a portion is done just by count the columns ~ the decimal point, climate pushing the decimal that countless spaces come the right. Finally, add the value of the final column (in this case, this thousandths column) to the portion as its denominator.

Putting The fraction In simplest Form

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


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

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

In the 2 prior examples, we currently knew what the GCF for the fountain was. However, you will do it usually need to do a bit of math to recognize the GCF of a fraction. There are multiple ways to uncover a fraction’s GCF, including listing, prime factorization, and the department method. One of the key ways to recognize the GCF the a fraction is to utilize the prime Factorization method. In the element factorization method, you will certainly multiply out the prime factors usual to both numerator and also denominator.

Finding The GCF

Let’s take it the fraction 18/24 because that example. Prime determinants that have the right to only be multiplied by one and itself room prime factors, so with prime factorization, you’ll want to perform out only the components which are prime numbers. In this case, the prime factors of 18 room 2 and also 3. These are additionally the the smallest numbers i beg your pardon you could multiply with each other to acquire 18 (2 x 3 x 3 = 18). Meanwhile, the prime components of 24 are likewise 2 and also 3 (2 x 2 x 2 x 3 = 24). Multiply 2 and also 3 with each other gets girlfriend the number 6, i beg your pardon you deserve to then divide right into 18/24 to acquire ¾.

It’s also possible to discover the greatest usual factor by just listing out components of the two numbers till you run out of feasible factors and also find the GCF. As an example, if you were provided the portion 180/210 you might look for the GCF by listing the end the determinants like so:


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

Let’s protect against here due to the fact that we may have the GCF already, or a method to discover it. The typical factors between 180 and also include, 2, 3, 5, 6, 10, and also 15. In this case, the greatest factor noted here is 15, and if we try multiplying it by 2 we get 30, which is certainly the greatest usual factor because that the fraction.

Dividing 30 right into 180/210 would obtain you the portion ⅞. Us could likewise have arrived on 30 for the GCF through multiplying with each other the numbers 2, 3, and also 5. Another way to find the GCF would have actually been just to store going and list out the factors until getting to 30, though as you can see this process can take rather a little bit of time compared to element factorization.

One other means of finding the GCF is the division Method. The department method involves dividing the two numbers up right into smaller chunks till you have actually numbers that can no longer be divided. As an example, let’s try finding the GCF the 144/280 making use of the division method.

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

72 and also 140 have much more common factors, for this reason we have the right to attempt to divide the number by two when more.

Doing this will give us: 36 and 70.

Once more, 36 and 70 quiet have usual factors between the two numbers, so let’s divide by 2 again to get 18 and 35. These 2 numbers nothing have any common factors besides one, therefore let’s protect against here and see what we have.

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

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

0.125 is simply 125/1000 when expressed as a fraction. Let’s division 125/1000 by the greatest typical factor. The GCF in this circumstances is 5, and also dividing 125/1000 gets us 25/200, which can be divided once more by 5 to gain 5/40 and also divided through 5 a final time to obtain ⅛.
