How to use Fractions Library (fraction.js) In Javascript

Using Math Operations

In this approach using the fraction.js library, we first create fraction objects for the given numerators and denominators. Then, we add these fractions using the add method provided by the library. Finally, we convert the result fraction to its simplest form using toFraction and display it in the console along with the input fractions.

Install the fraction.js library using the below command:

npm i fraction.js

Steps:

  • Utilize the Fraction constructor provided by the fraction.js library to create fraction objects for the given numerators and denominators.
  • Use the add method provided by the Fraction objects to add the fractions together. This method handles the addition internally and returns a new Fraction object representing the sum.
  • To ensure the result is in its simplest form, call the toFraction method on the sum fraction object. This method converts the fraction to its simplest form.
  • Output the result along with the input fractions to the console, showcasing the addition of fractions.

Example: The below example uses Fractions Library to perform the Addition of two fractions using JavaScript.

JavaScript 
const Fraction = require('fraction.js');
let num1 = 1;
let den1 = 500;
let num2 = 2;
let den2 = 1500;
let frac1 = new Fraction(num1, den1);
let frac2 = new Fraction(num2, den2);
let tempRes = frac1.add(frac2);
let res = tempRes.toFraction();
console.log(`${num1}/${den1} + ${num2}/${den2} is equal to ${res}`);

Output

1/500 + 2/1500 is equal to 1/300

Time Complexity: O(1)

Auxiliary Space: O(1)



Addition of Two Fractions using JavaScript

Fraction numbers in math are representations of parts of a whole, consisting of a numerator (the part being considered) and a denominator (the total number of equal parts). Add two fractions a/b and c/d and print the answer in simplest form.

Examples:  

Input:  1/2 + 3/2
Output: 2/1

Input:  1/3 + 3/9
Output: 2/3
