So I need to write test cases for a problem with multiplying, dividing, adding, & subtracting fractions but I just can't quite seem to get it correct that it works.

Here is part of the test file

```
//Multiply
if (f1.multiply(f2) == (-2/15))
{
System.out.println("test multiply: passed");
}
else
{
System.out.println("test multiply: FAILED");
}
```

**I am just having difficulties writing the first line so it works.

If I type:

`System.out.println(f1.multiply(f2));`

My answer is -2/15 so it is performing the procedure correctly.

Since f1 = 1/3 and f2 = (-2/5)

If I do .equals("-2/5") it compiles but then says it failed

Here is the other document if you need it, idk

```
//Multiply
public Fraction multiply(Fraction otherFraction)
{
int NumeratorMultiply = 0;
int DenominatorMultiply = 0;
NumeratorMultiply = numerator * otherFraction.getNumerator();
DenominatorMultiply = denominator * otherFraction.getDenominator();
return new Fraction(NumeratorMultiply, DenominatorMultiply);
}
```

Thanks
