__CONVERT DECIMAL TO FRACTION__

## How to convert decimal to fraction

#### Conversion stages

- Write the decimal fraction as a fraction of the digits to the right of the decimal period (numerator) and a power of 10 (denominator).
- Find the greatest common divisor (gcd) of the numerator and the denominator.
- Reduce the fraction by dividing the numerator and the denominator with the gcd.

#### Example #1

Convert 0.32 to fraction:

0.32 = 32/100

Find the greatest common divisor (gcd) of the numerator and the denominator:

gcd(32,100) = 4

Reduce the fraction by dividing the numerator and the denominator with the gcd:

0.32 = (32/4) / (100/4) = 8/25

#### Example #2

Convert 2.56 to fraction:

2.56 = 2+56/100

Find the greatest common divisor (gcd) of the numerator and the denominator:

gcd(56,100) = 4

Reduce the fraction by dividing the numerator and the denominator with the gcd:

2+56/100 = 2 + (56/4) / (100/4) = 2+14/25

#### Example #3

Convert 0.124 to fraction:

0.124 = 124/1000

Find the greatest common divisor (gcd) of the numerator and the denominator:

gcd(124,1000) = 4

Reduce the fraction by dividing the numerator and the denominator with the gcd:

0.124 = (124/4) / (1000/4) = 31/250

## How to convert repeating decimal to fraction

#### Example #1

Convert 0.333333… to fraction:

*x* = 0.333333…

10*x* = 3.333333…

10*x* – *x* = 9*x* = 3

*x* = 3/9 = 1/3

#### Example #2

Convert 0.0565656… to fraction:

*x* = 0.0565656…

100*x* = 5.6565656…

100*x* – *x* = 99*x* = 5.6

990*x* = 56

*x* = 56/990 = 28/495
