What Is 12/28 as a Decimal + Solution With Free Steps
The fraction 12/28 as a decimal is equal to 0.428.
Fractions are can be explained as a part of a pizza. Dividing a pizza into 12 equal pieces. By taking away 1 part of the pizza, we are left with 11 out of 12 parts of the pizza. This can be expressed as 11/12 of pizza, where 11 is the numerator and 12 is the denominator.
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 12/28.
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 done as follows:
Dividend = 12
Divisor = 28
Now, we introduce the most important quantity in our division process: 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 $\div$ 28
This is when we go through the Long Division solution to our problem. Given is the Long division process in Figure 1:
12/28 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 28, we can see how 12 is Smaller than 28, and to solve this division, we require that 12 be Bigger than 28.
This is done by multiplying the dividend by 10 and checking whether it is bigger than the divisor or not. If so, we calculate the Multiple of the divisor 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 28; this can be done as follows:
120 $\div$ 28 $\approx$ 4
28 x 4 = 112
This will lead to the generation of a Remainder equal to 120 – 112 = 8. Now this means we have to repeat the process by Converting the 8 into 80 and solving for that:
80 $\div$ 28 $\approx$ 2
28 x 2 = 56
This, therefore, produces another Remainder which is equal to 80 – 56 = 24. Now we must solve this problem to Third Decimal Place for accuracy, so we repeat the process with dividend 240.
240 $\div$ 28 $\approx$ 8
28 x 8 = 224
Finally, we have a Quotient generated after combining the three pieces of it as 0.428, with a Remainder equal to 16.
