Question

Write a program that will allow a user to multiply and divide pairs of integer fractions and provide the resulting fraction and the decimal representation as a double with 2 decimal places. Complete the SADITM prior to coding.

I N P U T

Please enter a numerator: 2 Please enter a denominator (zero is not allowed): 3 Please enter a numerator: 1 Please enter a denominator (zero is not allowed): 2

Output

2/3 * 1/2: The resulting fraction is 2/6.  

The decimal representation of 2/6 is 0.33

2/3 / 1/2: The resulting is fraction is 4/3.

The decimal representation of 4/3 is 1.33

pls can you solve this problem.

Explanation / Answer

Program in JAVA:-

import java.text.DecimalFormat;

import java.text.NumberFormat;

import java.util.Scanner;

public class DivisionDouble {

public static void main(String[] args) {

// TODO Auto-generated method stub

Scanner scanner=new Scanner(System.in);

System.out.println("Please enter a numerator:");

double num1=scanner.nextDouble();

System.out.println("Please enter a denominator (zero is not allowed):");

double denum1=scanner.nextDouble();

System.out.println("Please enter a numerator:");

double num2=scanner.nextDouble();

System.out.println("Please enter a denominator (zero is not allowed):");

double denum2=scanner.nextDouble();

double mulAns= (num1/denum1) * (num2/denum2);

double divAns=(num1/denum1) / (num2/denum2);

//Format the number for 2 decimal values.

NumberFormat formatter = new DecimalFormat("#0.00");

System.out.println(formatter.format(mulAns));

System.out.println(formatter.format(divAns));

}

}

OUTPUT:-

Please enter a numerator:
2
Please enter a denominator (zero is not allowed):
3
Please enter a numerator:
1
Please enter a denominator (zero is not allowed):
2
0.33
1.33
