With just a couple of simple calculations you deserve to convert 0.125 right into a fraction and then put it right into its simplest form.
You are watching: What is 0.125 as a fraction in simplest form
The simplest form of 0.125 as a portion is ⅛, yet how would you carry out this calculation? Let’s take it a look at the actions needed to transform 0.125 right into a fraction and then to put that fraction into its easiest form.
The first part that converting any type of decimal right into the simplest type of a fraction is to convert the decimal into a fraction. For this an initial conversion, any fraction will do, and also knowing around the nature of fractions and also decimals will aid you do these conversions. A conversion in between decimals and also fractions deserve to be made an extremely easily if you recognize the an enig behind their relationship to one another.
Converting A Decimal to A Fraction
Let’s take a quick look at just how you can transform a decimal to a fraction. Constantly remember that decimals are simply parts that a totality number. This property way that just all at once numbers have columns, like tens and hundreds, the numbers that come after the decimal point also have columns, and also these columns stand for what portion of a totality number the decimal is. The an initial column ~ the decimal suggest is the tenths place, while the 2nd column is the percentage percent place, and also so on.
So if one is provided the decimal 0.82, they recognize that 0.82 isn’t a whole number, just 82% of a entirety number. The number 1 is tantamount to 100%, which method that converting a decimal to a percentage, and also then to a fraction, is an extremely easy. Every you need to do is take it the decimal in the percentage percent place and also push it over to the best by two spaces, then placed the last column’s location value under the number. Because that example, 0.82 would end up being 82% or 82/100.
As an additional example, if you have actually the decimal 0.515, friend can conveniently make this a portion by noticing the the second five is in the thousandths place, which provides an tantamount to the portion 515/1000. Converting the decimal right into a fraction is done merely by counting the columns ~ the decimal point, then pushing the decimal that countless spaces come the right. Finally, add the worth of the last column (in this case, this thousandths column) come the fraction as that denominator.
Putting The fraction In most basic Form
Now the we have a fraction – 515/100 – we deserve to go about reducing the fraction, or placing it in its most basic form. 515/1000 is pretty messy, so how would one go around finding the smallest, most basic version that the fraction? This have the right to be done by finding what is recognized as the Greatest usual Factor or Greatest typical Divisor (GCF or GCD), and also then utilizing it to reduce a portion to its simplest terms.
The greatest common factor is the largest, best number the you have the right to divide evenly right into both the denominator and also numerator of the fraction. Let’s take the portion 515/1000 and distill it come its easiest form. In this case, the greatest common factor is 5. Splitting 5 right into 515 provides you 103/200.
Here’s a 2nd example. If you have actually the decimal 0.875, you could transform it to a portion (875/1000), and then discover the greatest common factor. In this situation the GCF is 125, so dividing 125 into both the numerator and denominator will obtain you ⅞.
In the two prior examples, we currently knew what the GCF for the fountain was. However, you’ll usually have to do a little bit of math to recognize the GCF the a fraction. There space multiple ways to uncover a fraction’s GCF, consisting of listing, prime factorization, and the department method. Among the main ways to recognize the GCF that a portion is to utilize the element Factorization method. In the element factorization method, you will multiply the end the element factors typical to both numerator and denominator.
Finding The GCF
Let’s take the portion 18/24 because that example. Prime determinants that can only be multiply by one and itself space prime factors, so v prime factorization, you’ll desire to perform out only the determinants which room prime numbers. In this case, the prime factors of 18 are 2 and 3. These are also the the smallest numbers i beg your pardon you could multiply together to gain 18 (2 x 3 x 3 = 18). Meanwhile, the prime determinants of 24 are additionally 2 and 3 (2 x 2 x 2 x 3 = 24). Multiply 2 and 3 together gets friend the number 6, i beg your pardon you can then divide right into 18/24 to gain ¾.
It’s also possible to find the greatest typical factor by just listing out factors of the 2 numbers until you run out of feasible factors and find the GCF. Together an example, if you were provided the portion 180/210 you could look because that the GCF by listing out the factors like so:
Factors of 180 (other than 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 avoid here due to the fact that we may have the GCF already, or a means to find it. The usual factors in between 180 and include, 2, 3, 5, 6, 10, and also 15. In this case, the best factor detailed here is 15, and if we shot multiplying it by 2 we gain 30, i beg your pardon is without doubt the greatest usual factor because that the fraction.
Dividing 30 into 180/210 would get you the fraction ⅞. We could also have arrived at 30 because that the GCF by multiplying with each other the numbers 2, 3, and also 5. Another way to find the GCF would have been simply to save going and also list out the determinants until reaching 30, though together you can see this procedure can take quite a bit of time compared to prime factorization.
One other way of detect the GCF is the department Method. The division method involves dividing the 2 numbers up right into smaller chunks till you have actually numbers that deserve to no longer be divided. As an example, let’s shot finding the GCF that 144/280 making use of the department method.
Dividing 144 and also 280 by 2 offers us: 72 and 140.
72 and also 140 have an ext common factors, so we have the right to attempt to divide the numbers by two as soon as more.
Doing this will give us: 36 and 70.
Once more, 36 and 70 tho have common factors between the 2 numbers, therefore let’s divide by 2 again to obtain 18 and 35. These two numbers nothing have any type of common components besides one, so let’s prevent here and see what us have.
Let’s multiply whatever together: 2 x 2 x 2 = 8. Now we have the right to divide 144/280 by 8 to get 18/35.
Now let’s apply everything we’ve learned to converting 0.125 into the simplest form of a fraction.

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