## What is 1/4 together a Decimal?

When we convert a portion into decimal form, we transform it into a number that has denominator 1. Therefore the molecule takes a kind that has actually a decimal in it.

The decimalform of\(\dfrac14\,\) is 0.25

Let's see exactly how to gain that.

**How to adjust ¼ together a decimal**

The fraction\(\dfrac14\,\)can be convert to a form with denomiator 1 by detect its decimal form.

To acquire the decimal form of \(\dfrac14\,\), various methods have the right to be used.

**Method 1**

In this method, we use lengthy division.

Here, molecule = 1 and Denominator = 4. Let's divide 1 by 4

So,

\(\dfrac14=0.25.....\textDecimal form\)

We can use this an approach forconverting any fraction to decimal form.

**Method 2**

The other method is to transform the portion into the equivalent portion with denominator together a strength of 10

The first power that 10 is 10 which is nota lot of of 4. So, let's look at the second multiple, 100, i m sorry is a lot of of 4

In thefraction\(\dfrac14\), denominator = 4

\beginalign \dfrac14&=\dfrac1\times 254\times 25\\&=\dfrac25100\endalign

Now, observe that there are 2 zeros in the denominator.

So, there will certainly be two digits ~ decimal in the numerator.

\(\dfrac14=0.25\)

Similarly, if us havethefraction\(\dfrac38\), us can convert it right into decimal by converting it into its equivalent portion with denominator 1000

\beginalign \dfrac38&=\dfrac3\times 1258\times 125\\&=\dfrac3751000\\&=0.375\endalign

We have the right to even convert a decimal to fraction. For this, we consider the variety of digits ~ the decimal.

Example: take 0.65. There room two digits after the decimal.

\beginalign 0.65&=\dfrac65100\\&=\dfrac1320\endalign

Example 1 |

Harry is struggling come express\(\dfrac23\,\) together decimal. Deserve to you help him by using long department method to convert a fraction to decimal?

**Solution**

As denominator is 3, which is no a aspect of 100, we will certainly convert\(\dfrac23\,\) as a decimal by lengthy division.

The quotient is 0.6666.....= \(0.\overline6\cdot\cdot \)Digit 6 is recurring right here as the remainder is walking on repeating.

So, us round turn off 0.6666..... To 0.67 (rounding off upto 2 decimal places).
