calculate the ratios of its elements that are positive, negative, and zero. Print the decimal value of each fraction on a new line with places after the decimal.

Given an array of integers, calculate the ratios of its elements that are positive, negative, and zero. Print the decimal value of each fraction on a new line with  places after the decimal.

function plusMinus(arr) {

  let minusNumber = 0

  let plusNumber = 0

  let ZeroNumber = 0

 

  for(let i = 0 ; i<arr.length; i++){

      if(arr[i]<0){

          minusNumber+=1

      }else if (arr[i]>0){

          plusNumber+=1

      }else{

          ZeroNumber+=1

      }

     

  }

 

  let  plus = plusNumber/arr.length

  let zero = ZeroNumber/arr.length

  let minus = (minusNumber/arr.length)

  console.log(plus.toFixed(6));

  console.log(minus.toFixed(6))

  console.log(zero.toFixed(6));
