With simply a few simple calculations you have the right to convert 0.125 right into a fraction and then put it right into its simplest form.
You are watching: 125 as a fraction in simplest form
The simplest kind of 0.125 as a fraction is ⅛, yet exactly how would you do this calculation? Let’s take it a look in ~ the actions needed to transform 0.125 right into a portion and then to placed that portion into its most basic form.
The an initial part that converting any decimal right into the simplest form of a fraction is to transform the decimal into a fraction. For this first conversion, any fraction will do, and also knowing about the properties of fractions and decimals will assist you do these conversions. A conversion in between decimals and also fractions deserve to be made very easily if you know the an enig behind their partnership to one another.
Converting A Decimal come A Fraction
Let’s take it a fast look at just how you can convert a decimal to a fraction. Always remember that decimals are just parts that a whole number. This property method that just in its entirety numbers have columns, favor tens and hundreds, the numbers the come ~ the decimal allude also have actually columns, and these columns represent what part of a whole number the decimal is. The first column after the decimal allude is the one per 10 place, when the second column is the percentage percent place, and so on.
So if one is offered the decimal 0.82, they know that 0.82 isn’t a whole number, just 82% that a totality number. The number 1 is tantamount to 100%, which means that converting a decimal come a percentage, and also then to a fraction, is really easy. All you have to do is take the decimal in the percentage percent place and also push it over to the ideal by 2 spaces, then placed the critical column’s location value under the number. Because that example, 0.82 would end up being 82% or 82/100.
As one more example, if you have the decimal 0.515, girlfriend can conveniently make this a portion by noticing the the second five is in the thousandths place, which renders an identical to the fraction 515/1000. Converting the decimal into a fraction is done just by counting the columns after ~ the decimal point, climate pushing the decimal that many spaces come the right. Finally, add the value of the final column (in this case, this thousandths column) to the fraction as its denominator.
Putting The fraction In easiest Form
Now the we have actually a portion – 515/100 – we have the right to go around reducing the fraction, or placing it in its simplest form. 515/1000 is pretty messy, so just how would one go about finding the smallest, simplest version that the fraction? This deserve to be done by detect what is known as the Greatest common Factor or Greatest common Divisor (GCF or GCD), and then using it to alleviate a fraction to its simplest 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 of the fraction. Let’s take it the fraction 515/1000 and also distill it come its simplest form. In this case, the greatest typical factor is 5. Dividing 5 right into 515 gives you 103/200.
Here’s a 2nd example. If you have the decimal 0.875, girlfriend could transform it to a fraction (875/1000), and also then uncover 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’ll usually have to do a bit of math to recognize the GCF of a fraction. There are multiple means to uncover a fraction’s GCF, including listing, element factorization, and also the department method. One of the main ways to identify the GCF the a portion is to make use of the element Factorization method. In the prime factorization method, you will multiply the end the element factors usual to both numerator and denominator.
Finding The GCF
Let’s take it the fraction 18/24 for example. Prime factors that deserve to only be multiplied by one and itself room prime factors, so through prime factorization, you’ll want to list out just the factors which space prime numbers. In this case, the prime components of 18 room 2 and 3. These are also the smallest numbers which you can multiply together to gain 18 (2 x 3 x 3 = 18). Meanwhile, the prime components of 24 are also 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, which you deserve to then divide into 18/24 to obtain ¾.
It’s also possible to find the greatest typical factor by simply listing out components of the two numbers until you operation out of feasible factors and also find the GCF. Together an example, if friend were given the portion 180/210 you can look because that the GCF through listing out the components like so:
Factors the 180 (other 보다 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 due to the fact that we may have the GCF already, or a means to uncover it. The typical factors between 180 and also include, 2, 3, 5, 6, 10, and also 15. In this case, the best factor listed here is 15, and also if we shot multiplying that by 2 we acquire 30, which is certainly the greatest usual factor because that the fraction.
Dividing 30 into 180/210 would get you the fraction ⅞. Us could additionally have arrived on 30 for the GCF by multiplying with each other the number 2, 3, and 5. Another means to discover the GCF would have been simply to save going and list out the factors until reaching 30, though as you deserve to see this process can take fairly a bit of time contrasted to element factorization.
One other way of recognize the GCF is the division Method. The department method involves dividing the two numbers up right into smaller chunks until you have actually numbers that deserve to no longer be divided. Together an example, let’s shot finding the GCF that 144/280 using the department method.
Dividing 144 and also 280 by 2 provides us: 72 and 140.
72 and also 140 have much more common factors, therefore we have the right to attempt to divide the number by two once more.
Doing this will give us: 36 and 70.
Once more, 36 and 70 still have usual factors in between the two numbers, so let’s division by 2 again to obtain 18 and 35. These 2 numbers don’t have any kind of common determinants besides one, therefore let’s prevent here and also see what we have.
Let’s multiply whatever together: 2 x 2 x 2 = 8. Now we have the right to divide 144/280 through 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 when expressed together a fraction. Let’s division 125/1000 through the greatest usual 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 an ext by 5 to get 5/40 and also divided through 5 a final time to acquire ⅛.
