1 4 In A Decimal

Four friends, Rocky, Rooney, David, and Sam divided a donut equally amongst themselves. Sam asked, "What portion of the donut do I have?" Rocky replied, " I fourth." Sam asked over again, "Is information technology possible to write it in a form that has denominator 1?".

Let us aid Sam resolve his query in mere few minutes.

This section focuses on representing \( \frac{i}{four} \) as a decimal forth with some interactive examples and questions on the representation of \( \frac{three}{8} \) equally a decimal, \( \frac{2}{3} \) as a decimal, and decimal to fraction conversion. Do not forget to try do questions at the end of the page for a quick fun revision.

Lesson Plan

What is i/4 as a Decimal?

When we convert a fraction into decimal form, nosotros convert it into a number that has denominator 1. So the numerator takes a grade that has a decimal in it.

The decimal class of \(\dfrac{1}{4}\,\) is 0.25

Let's come across how to get that.


How to change ¼ equally a decimal

The fraction \(\dfrac{1}{4}\,\)tin can be converted to a grade with denomiator 1 by finding its decimal form.

To get the decimal form of \(\dfrac{ane}{iv}\,\), different methods can be used.

Method 1

In this method, nosotros use long division.

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

1/4 to decimal

So,

\(\dfrac{ane}{four}=0.25.....\text{Decimal form}\)

Nosotros tin use this method for converting any fraction to decimal course.

Method 2

The other method is to catechumen the fraction into its equivalent fraction with denominator as a power of 10

The start ability of 10 is x which is non a multiple of 4. So, let'south look at the second multiple, 100, which is a multiple of 4

In the fraction \(\dfrac{1}{4}\), denominator = 4

\begin{align} \dfrac{1}{4}&=\dfrac{1\times 25}{4\times 25}\\&=\dfrac{25}{100}\end{align}

Now, observe that at that place are two zeros in the denominator.

So, there will exist two digits after decimal in the numerator.

\(\dfrac{1}{4}=0.25\)

Similarly, if we have the fraction \(\dfrac{three}{viii}\), nosotros tin can convert it into decimal by converting information technology into its equivalent fraction with denominator thousand

\begin{align} \dfrac{3}{viii}&=\dfrac{3\times 125}{viii\times 125}\\&=\dfrac{375}{m}\\&=0.375\end{align}

We can even convert a decimal to fraction. For this, we consider the number of digits subsequently the decimal.

Instance: Have 0.65. At that place are two digits after the decimal.

\begin{align} 0.65&= \dfrac{65}{100}\\&=\dfrac{13}{20}\end{marshal}

important notes to remember

  1. Decimals are used to represent fractions which have value less than 1
  2. Visualization of 0.25 on a number line:

Solved Examples

Harry is struggling to express \(\dfrac{ii}{3}\,\) every bit decimal. Can you help him by using long partition method to convert a fraction to decimal?

Solution

Equally denominator is 3, which is not a factor of 100, we will convert \(\dfrac{2}{iii}\,\) equally a decimal past long partitioning.

decimal form of 2/3

The quotient is 0.6666.....= \(0.\overline{6}\cdot\cdot \)Digit six is recurring here equally the residue is going on repeating.

So, we round off 0.6666..... to 0.67 (rounding off upto 2 decimal places).

\(\therefore\dfrac{2}{iii}=0.67\)

Mia wants to express \(\dfrac{3}{8}\,\) every bit a decimal number using long division. Help her to achieve the right answer.

Solution

Mia needs to split up iii past 8 and proceed dividing till she gets the remainder 0

decimal form of 3/8

\(\therefore\)Decimal form of \(\dfrac{3}{eight}\) is 0.375

Thinking out of the box

Detect decimal form of fractions \(\dfrac{1}{5}\) and \(\dfrac{1}{7}\). What departure did you notice in their decimal forms?

(Hint: Observe the remainders in both the cases.)
