    JavaScript Solution

    function plusMinus(arr) {
    let [pos, neg, zer] = [0,0,0];
    for(let i = 0; i < arr.length; i++){
        if(arr[i] > 0)pos++;
        else if(arr[i] < 0)neg++;
        else if(arr[i] === 0) zer++;
    }
    let ratios = [pos, neg, zer];
    ratios.forEach(val => {
        console.log((val/arr.length).toFixed(6));
    })
}

    here is a solutions with java

    int zeros = 0; int positives = 0; int negatives = 0;

    for(int numbers : arr){
    if(numbers == 0){
        positives ++;
    }else if(numbers < 0){
        negatives ++;
    }else{
        zeros++;
    }
}
int total = arr.size();

double proportionPositives = (double) positives / total;
double proportionNegatives = (double) negatives/ total;
double proportionzeros = (double) zeros / total;

System.out.printf("%.6f\n", proportionzeros);
System.out.printf("%.6f\n", proportionNegatives);
System.out.printf("%.6f\n", proportionPositives);

    **here is python code for this problem ** def plusMinus(arr): # Write your code here lent = len(arr) zer,pos,neg = [],[],[] for i in arr: if i > 0: pos.append(i) elif i<0: neg.append(i) else: zer.append(i) p=float(len(pos))/lent n=float(len(neg))/lent z=float(len(zer))/lent

    print(f"{p:6f}")   
print(f"{n:6f}")   
print(f"{z:6f}")

    function plusMinus(arr) {

        const total = arr.length;

    const totalArray = [0, 0, 0];

        arr.forEach((item) => {

            if (item === 0) {

            totalArray[2]++;

        } else if (item > 0) {

  totalArray[0]++;

} else {

  totalArray[1]++;

}

    });

    totalArray.forEach((count) => {

    const newItem = count / total;

console.log(newItem.toFixed(6));

    plusMinus([-4, 3, -9, 0, 4, 1]);
