What Is 4/31 as a Decimal + Solution With Free Steps
The fraction 4/31 as a decimal is equal to 0.129.
The operation of division between two numbers can be represented using the fraction. It is mathematically written in the form of p/q. Here ‘p‘ is the numerator and ‘q‘ is the denominator of the fraction.
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 4/31.
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 = 4
Divisor = 31
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 = 4 $\div$ 31
This is when we go through the Long Division solution to our problem. The long division for fraction 4/31 is given in figure 1.
4/31 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 4 and 31, we can see how 4 is Smaller than 31, and to solve this division, we require that 4 be Bigger than 31.
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 4, which after getting multiplied by 10 becomes 40.
We take this 40 and divide it by 31; this can be done as follows:
40 $\div$ 31 $\approx$ 1
31 x 1 = 31
This will lead to the generation of a Remainder equal to 40 – 31 = 9. Now this means we have to repeat the process by Converting the 9 into 90 and solving for that:
90 $\div$ 31 $\approx$ 2
31 x 2 = 62
This, therefore, produces another Remainder equal to 90 – 62 = 28. Now we must solve this problem to Third Decimal Place for accuracy, so we repeat the process with dividend 280.
280 $\div$ 31 $\approx$ 9
31 x 9 = 279
Finally, we have a Quotient generated after combining the three pieces of it as 0.129, with a Remainder equal to 1.
