Arithmetical operations task with Objects

I've checked many stackOverflow questions about operations with objects but I haven't find the solution.

My task is to multiply and divide two objects with these constructors:

public class Fraction {
    private int denom;
    private int counter;

    public Fraction() {
        this.counter = 0;
        this.denom = 1;
    }

    public Fraction(int counter) {
        this.counter = counter;
        this.denom = 1;
    }

    public Fraction(int counter, int denom) {
            this.counter = counter;
        if (denom == 0) {
            this.denom = 1;
        } else
            this.denom = denom;
    }
}

What would be inside the "multiply" and "divide" methods?

public Fraction multiply(Fraction other) {

}

public Fraction divide(Fraction other) {

}

if this is what I need to use:

Fraction frac1 = new Fraction (2);
Fraction frac2 = new TortSzam(3,4);
fracResult = frac1.divide(frac2);

and the result is: 2.6666666666666665

What I tried by other StackOverflow Questions:

public Fraction multiply(Fraction other) {
        final Fraction multi = this;
        BigInteger result = new BigInteger;
        result.multiply(other);
}

But didn't work.

Thanks in advance.

Multiplying two fractions just means multiplying the numerators, and then dividing that product by the multiplication of the denominators. So you may try:

public Fraction multiply(Fraction other) {
    int counter = other.getCounter() * this.counter;
    int denim = other.getDenominator() * this.denom;

    return new Fraction(counter, denom);
}

I will leave the implementation of division up to you. As a hint, the code would be very similar to the above except that you would use the inverse of one (but not both) of the two fraction inputs.
