To convert a decimal into a fraction, we need to first write the given decimal in the form of a fraction, by adding a denominator 1. Then we need to multiply both numerator and denominator with the multiples of 10, to remove decimal (.) from the given number. For example, 1.9 is a decimal number, then the equivalent fraction will be 19/10. We cannot simply 19/10 further.

**Decimal:** In terms of a computer, decimal numbers are the numbers that have a base 10. But in Mathematics, a decimal number is a number that has a dot(.) or decimal point between the digits. Basically, decimals are nothing but fractions with denominators as 10 or multiples of 10. For example, 3.2, 10.9, 55.1, 1.28, 9.234, etc., are decimals.

**Fractions: **Fraction is a part of a whole number. It is denoted as a ratio of two numbers a/b, where a and b are integers, also b≠0. The two numbers are called the numerator and denominator. For example, 1/2 is a part of 1, 3/5 is a part of 3, etc. We can perform all the arithmetic operations on fractions. There are three types of fractions, Proper, Improper and Mixed.

## How to Convert Decimal into Fractions?

Now let us learn the steps to convert the decimal into fractions.

- First write the given decimal in the form of a ratio (p/q), where the denominator is equal to 1.
- Now multiply the numerator and denominator by multiples of 10, for every decimal point, such that the decimal in the numerator becomes a whole number. (If there are two numbers after the decimal point, then multiply by 100/100)
- Simply the resulting fraction

## Solved Examples

Solve problems based on conversion of decimal to fraction and fraction to decimal are given here. These examples of decimal to fraction conversions will help you in better understanding of the concept.

**Question 1: Find the fraction form of the decimal 0.7**

**Solution: **Given, decimal number 0.7, we need to find the fraction for 0.7.

We can also find a number of equivalent fractions by finding its multiples.

0.7 = 7/10

Now multiply, 7/10 by 2, both in numerator and denominator, then we get;

(7×2)/(10×2) = 14/20

To find more equivalent fractions, let us multiply 7/10 by 5 and 10 both in numerator and denominator.

7×5/10×5 = 35/50

7×10/10×10 = 70/100

Therefore, the fractions of 0.7 decimal are 7/10, 35/50, 70/100.

**Question 2: Convert 7.15 into a fraction.**

**Solution:** Given, 7.15 is a decimal number.

Multiply and divide 7.15 by 100.

7.15 × 100/100 = 715/100

If we simplify it more, we get;

143/20

We can also find the equivalent fractions by multiplying the numerator and denominator by 2. Such as;

143×2/20×2 = 286/40

So, 7.15 equivalent fractions are 715/100, 143/20 and 286/40.

**Question 3: Convert 3.35 into a fraction.**

Solution: Following the above steps:

3.35/1

Since there are two numbers after the decimal point, therefore, multiply 3.35/1 by 100 in numerator and denominator.

(3.35/1)x(100/100) = 335/100 = 67/20

**Question 4: Convert 1.625 into a mixed fraction.**

Solution: We can write 1.625 as 1.625/1

Multiply by 1000 to remove decimal up to three places

1.625/1 x (1000/1000) = 1625/1000

Simplifying 1625/1000 we get;

⇒ 13/8

Now converting into a mixed fraction.

13/8 = 1 5/8

Hence, 1 5/8 is the mixed fraction equivalent to 1.625.

## Repeating Decimal to Fraction

To convert a usual decimal number to a fraction is an easy method. But to convert a repeating or recurring number to a fraction is a lengthy task. For example, 0.666…, 4.17777…, 0.56111.., are recurring numbers. Let us learn to convert recurring decimal to fraction with the help of an example.

**Example: Convert 0.6666… Into fraction.**

**Solution:** Let x = 0.6666

Now multiply x by 10 on both sides.

10 x = 6.666…

Subtracting x from 10x, we get;

10x-x = 6.666…-0.6666

9x = 6.000

x = 6/9 = ⅔
