# What Is 2/21 as a Decimal + Solution With Free Steps

The fraction 2/21 as a decimal is equal to 0.095.

Rational numbers are numbers that can be expressed in the form of a ratio. At the same time, irrational numbers are numbers that cannot be expressed in the form of a fraction. Furthermore, the common thing between them is that both are real numbers, meaning they can be expressed on the number line.

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 2/21.

## Solution

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 = 2

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 = 2 $\div$ 21

This is when we go through the Long Division solution to our problem.

## 2/21 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 2 and 21, we can see how 2 is Smaller than 21, and to solve this division, we require that 2 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 2, which after getting multiplied by 100 becomes 200.

We take this 200 and divide it by 21; this can be done as follows:

200 $\div$ 21 $\approx$ 9

Where:

21 x 9 = 189

This will lead to the generation of a Remainder equal to 200 – 189 = 11. Now this means we have to repeat the process by Converting the 11 into 110 and solving for that:

110 $\div$ 21 $\approx$ 5

Where:

21 x 5 = 105

This, therefore, produces another Remainder which is equal to 110 – 105 = 5.

Finally, we have a Quotient generated after combining the three pieces of it as 0.095=z, with a Remainder equal to 5.
