# Converting a proper fraction to mixed fraction - JavaScript

JavascriptWeb DevelopmentFront End TechnologyObject Oriented Programming

## Proper Fraction

A proper fraction is the one that exists in the p/q form (both p and q being natural numbers)

## Mixed Fraction

Suppose we divide the numerator of a fraction (say a) with its denominator (say b), to get quotient q and remainder r.

The mixed fraction form for fraction (a/b) will be −

qrb

And it is pronounced as "q wholes and r by b”.

We are required to write a JavaScript function that takes in an array of exactly two numbers representing a proper fraction and our function should return an array with three numbers representing its mixed form

## Example

Following is the code −

const arr = [43, 13];
const properToMixed = arr => {
const quotient = Math.floor(arr / arr);
const remainder = arr % arr;
if(remainder === 0){
return [quotient];
}else{
return [quotient, remainder, arr];
};
};
console.log(properToMixed(arr));

## Output

Following is the output in the console −

[ 3, 4, 13 ]
