Four friends, Rocky, Rooney, David, and Sam separated a donut equally amongst themselves. Sam asked, "What portion of the donut carry out I have?" Rocky replied, " One fourth." Sam asked again, "Is it feasible to create it in a kind that has denominator 1?".

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. Therefore the numerator takes a kind that has a decimal in it.
The decimalform of\(\dfrac14\,\) is 0.25
Let's see how to acquire that.
How to adjust ¼ as a decimal
The fraction\(\dfrac14\,\)can be convert to a kind with denomiator 1 by recognize its decimal form.
To obtain the decimal form of \(\dfrac14\,\), various methods have the right to be used.
In this method, us use long division.
Here, numerator = 1 and Denominator = 4. Let's division 1 by 4
We have the right to use this method forconverting any fraction to decimal form.
The other an approach is to convert the fraction into that is equivalent portion with denominator together a strength of 10
The first power the 10 is 10 which is nota multiple of 4. So, let's look at the second multiple, 100, i beg your pardon is a multiple 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 be two digits after ~ decimal in the numerator.
Similarly, if us havethefraction\(\dfrac38\), us can transform it right into decimal by convert it right into its equivalent fraction with denominator 1000
\beginalign \dfrac38&=\dfrac3\times 1258\times 125\\&=\dfrac3751000\\&=0.375\endalign
We deserve to even transform a decimal come fraction. For this, we think about the number of digits after the decimal.
Example: take 0.65. There room two digits after the decimal.
Harry is struggling come express\(\dfrac23\,\) as decimal. Can you help him by making use of long division method to transform a fraction to decimal?
As denominator is 3, which is not a aspect of 100, we will convert\(\dfrac23\,\) together a decimal by long division.
The quotient is 0.6666.....= \(0.\overline6\cdot\cdot \)Digit 6 is recurring here as the remainder is going on repeating.
So, us round turn off 0.6666..... Come 0.67 (rounding off upto 2 decimal places).
