What Is 10/21 as a Decimal + Solution With Free Steps
The fraction 10/21 as a decimal is equal to 0.476.
The basic arithmetic operation of the division of two numbers is used everywhere. It is sometimes easier and more useful to express this in the form of a fraction p/q, where p is a numerator and q is the denominator. It is the same as the usual p $\boldsymbol\div$ q notation.
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 10/21.
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 = 10
Divisor = 21
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 = 10 $\div$ 21
This is when we go through the Long Division solution to our problem.
10/21 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 10 and 21, we can see how 10 is Smaller than 21, and to solve this division, we require that 10 be Bigger than 21.
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 10, which after getting multiplied by 10 becomes 100.
We take this 100 and divide it by 21; this can be done as follows:
100 $\div$ 21 $\approx$ 4
21 x 4 = 84
This will lead to the generation of a Remainder equal to 100 – 84 = 16. Now this means we have to repeat the process by Converting the 16 into 160 and solving for that:
160 $\div$ 21 $\approx$ 7
21 x 7 = 147
This, therefore, produces another Remainder which is equal to 160 – 147 = 13. Now we must solve this problem to Third Decimal Place for accuracy, so we repeat the process with dividend 130.
130 $\div$ 21 $\approx$ 6
21 x 6 = 126
Finally, we have a Quotient generated after combining the three pieces of it as 0.476, with a Remainder equal to 4.
