Write a program to convert a fraction to a decimal. Have your program ask for the numerator first, then the denominator. Make su
Anton [14]
<h2>Answer:</h2>

import java.util.Scanner;

public class FractionToDecimal {

   public static void main(String[] args) {

       Scanner input = new Scanner(System.in);

       

       System.out.println("Please enter the numerator");

       double numerator = input.nextDouble();

       System.out.println("Please enter the denominator");

       double denominator = input.nextDouble();

       

       if(denominator == 0){

           System.err.println("ERROR - Cannot divide by zero.");

       }

       else {

           System.out.println("The result is " + (numerator/denominator));

       }

       

   }

   

}

<h2>Explanation:</h2>

// import the Scanner class to allow for user input

import java.util.Scanner;

// 1. Declare a class

public class FractionToDecimal {

   // 2. Write the main method

   public static void main(String[] args) {

       

       // 3. Create an object of the Scanner class called <em>input</em>

       Scanner input = new Scanner(System.in);

       

       // 4. Prompt the user to supply the numerator

       System.out.println("Please enter the numerator");

       

       // 5. Declare and initialize a variable <em>numerator </em>to hold the numerator

       // supplied by the user.

       // The numerator is of type double since the program does not

       // specify any. With a double both integer and floating point numbers

       // will be supported.

       double numerator = input.nextDouble();

       

       // 6. Prompt the user to enter the denominator

       System.out.println("Please enter the denominator");

       // 7. Declare and initialize a variable <em>denominator </em>to hold the

       // denominator supplied by the user.

       // The denominator is also of type double since the program does not

       // specify any. With a double, both integer and floating point numbers

       // will be supported.

       double denominator = input.nextDouble();

       // 8. Check if the denominator is or is not zero.

       // if it is zero, display an error message        

       if(denominator == 0){

           System.err.println("ERROR - Cannot divide by zero.");

       }

       // if it is not zero, then print out the result of the division

       else {

           System.out.println("The result is " + (numerator/denominator));

       }

       

   }                       // end of main method

   

}                            // end of class declaration

Please Note:

The code above has been written in Java.

The explanation segment contains comments to explain every line of the code.

But a few things are still worth noting;

i. Dividing the numerator by the denominator will convert a fraction to decimal.

ii. The object of the Scanner class <em>input </em> is used to get the inputs (numerator and denominator) from the user. Since the inputs are going to be integers or doubles, the nextDouble() method of the the Scanner class is used.

iii. If the denominator is zero, an error message will be displayed. I have used the System.err.println() method for that rather than the regular System.out.println() method. The difference is that the former will print out the error text in red color.

iv. Notice also that the else statement in the code will perform the division and also print out the result of the division along side with some text.

<em>Hope this helps!</em>

The terminology used to describe a possible path to resolution to a problem from one end to the other is called what?
Ede4ka [16]

The terminology used to describe a possible path to a resolution to a problem from one end to the other is called a solution.

The earliest age of technology. It can be defined as the time between 3000 B.C. and 1450 A.D. When humans first started communicating, they would try to use language to make simple pictures – petroglyphs to tell a story, map their terrain, or keep accounts such as how many animals one owned, etc.

Can run mobile-style apps in the area known as the start screen, while running traditional software in the more familiar desktop
Travka [436]
The correct answer: Yes, mobile-style apps can run in a personal computer's desktop.

That is possible by means of a desktop application called emulatator. An emulator like Bluestacks allows a personal computer to run mobile-style apps by acting as a virtual drive in the personal computer's harddisk. 

Emulation is successful if the system requirements of the mobile-application is met by the personal computer's system attributes such as Random Access Memory abundance, Random Access Memory speed, Processing speed (in some cases core abundance e.g. core 2) etc. 

Some mobile-applications do not work in the personal computer's desktop, however, if this application requires platform specific functions such as mobile device's network provider etc.
