# Decimal to Fraction Program in java

In this post, we will learn Decimal to Fraction Program in java Programming language.

## Question:

Bobby is in her 2nd grade and has just started to learn about fractions. Whenever she comes across a decimal number she is curious to know the equivalent fraction for that number. Help her to convert a decimal number into a fraction. Write a program that accepts a decimal number and prints the fraction equivalent in the simplified/reduced form.

Sample input1

12.5

Sample output 1(Improper Fraction- where the numerator is greater than denominator)

Fraction: 25/2

Sample input 2

0.625

Sample output 2(Proper Fraction- where the numerator is lesser than denominator)

Fraction: 5/8

Sample input 3

3

Sample output 3

Input a decimal number

### CODE:–

```import java.util.*;
public class Main
{
public static void fraction(double x)
{   Main obj=new Main();
String a=""+x;
String splits[]=a.split("\\.");
int b=splits.length();
int denominator=(int)Math.pow(10, b);
int numerator=(int)(x*denominator);
int gcd=obj.getGCD(numerator, denominator);
String fraction=""+numerator/gcd+"/"+denominator/gcd;
System.out.println("Fraction: "+fraction);
}
int getGCD(int n1, int n2)
{
if(n2==0)
{
return n1;
}
return getGCD(n2, n1%n2);
}
public static void main (String[] args) {
Scanner sc=new Scanner(System.in);
double a=sc.nextDouble();
if(a==(int)(a))
{
System.out.println("Input a decimal number");
}
else{
fraction(a);
}
}
}```
