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.
In this method, us use lengthy division.
Here, numerator = 1 and Denominator = 4. Let's division 1 through 4
(dfrac14=0.25..... extDecimal form)
We can use this method forconverting any portion to decimal form.
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.
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.

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).
