What is 1/4 as a Decimal?


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

The decimalform of(dfrac14,) is 0.25

Let's see just how to acquire that.


How to readjust ¼ together a decimal


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

To acquire the decimal kind of (dfrac14,), various methods deserve to be used.

Method 1

In this method, us use lengthy division.

Here, numerator = 1 and Denominator = 4. Let's division 1 through 4

*

So,

(dfrac14=0.25..... extDecimal form)

We can use this method forconverting any portion to decimal form.

Method 2

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

The an initial power the 10 is 10 which is nota multiple of 4. So, let's look at the 2nd multiple, 100, which is a lot of of 4

In thefraction(dfrac14), denominator = 4

*

eginalign dfrac14&=dfrac1 imes 254 imes 25\&=dfrac25100endalign

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

So, there will be 2 digits after ~ decimal in the numerator.

(dfrac14=0.25)

Similarly, if we havethefraction(dfrac38), we can transform it into decimal by converting it into its equivalent portion with denominator 1000

eginalign dfrac38&=dfrac3 imes 1258 imes 125\&=dfrac3751000\&=0.375endalign

We can even transform a decimal come fraction. Because that this, we think about the number of digits after ~ the decimal.

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

eginalign 0.65&=dfrac65100\&=dfrac1320endalign

Example 1

Harry is struggling come express(dfrac23,) together decimal. Can you help him by utilizing 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.overline6cdotcdot )Digit 6 is recurring here as the remainder is going on repeating.

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