What Is 12/13 as a Decimal + Solution With Free Steps
The fraction 12/13 as a decimal is equal to 0.923.
Decimals can be written in form of a fraction by adding 1 at the place of the decimal point in the denominator and the number of zeros depending upon the number of digits present after the decimal point. Similarly, fractions can be converted into decimal numbers by simply dividing.
Here, we are more interested in the division types that result in a Decimal value, as this can be expressed as a Fraction. We see fractions as a way of showing two numbers having the operation of Division between them that result in a value that lies between two Integers.
Now, we introduce the method used to solve said fraction to decimal conversion, called Long Division which we will discuss in detail moving forward. So, let’s go through the Solution of fraction 12/13.
First, we convert the fraction components i.e., the numerator and the denominator, and transform them into the division constituents i.e., the Dividend and the Divisor respectively.
This can be seen done as follows:
Dividend = 12
Divisor = 13
Now, we introduce the most important quantity in our process of division, this is the Quotient. The value represents the Solution to our division, and can be expressed as having the following relationship with the Division constituents:
Quotient = Dividend $\div$ Divisor = 12 $\div$ 13
This is when we go through the Long Division solution to our problem. The long division process is shown below in figure:
12/13 Long Division Method
We start solving a problem using the Long Division Method by first taking apart the division’s components and comparing them. As we have 12, and 13 we can see how 12 is Smaller than 13, and to solve this division we require that 12 be Bigger than 13.
This is done by multiplying the dividend by 10 and checking whether it is bigger than the divisor or not. And if it is then we calculate the Multiple of the divisor which is closest to the dividend and subtract it from the Dividend. This produces the Remainder which we then use as the dividend later.
Now, we begin solving for our dividend 12, which after getting multiplied by 10 becomes 120.
We take this 120 and divide it by 13, this can be seen done as follows:
120 $\div$ 13 $\approx$ 9
13 x 9 = 117
This will lead to the generation of a Remainder equal to 120 – 117 = 3, now this means we have to repeat the process by Converting the 3 into 30 and solving for that:
30 $\div$ 13 $\approx$ 2
13 x 2 = 26
This, therefore, produces another remainder which is equal to 30 – 26 = 4. Now we must solve this problem to Third Decimal Place for accuracy, so we repeat the process with dividend 40.
40 $\div$ 13 $\approx$ 3
13 x 3 = 39
Finally, we have a Quotient generated after combining the three pieces of it as 0.923 = z, with a Remainder equal to 1.
