##### Functions Returning A String - Swift

I'm doing a fraction calculator and I'm trying to add 2 fractions when I put in my fractions it just adds my Whole numbers only and nothing else if my fraction is 2 3/4 + 2 3/5 it add the whole numbers and outputs 4

``````    var firstStep = firstDenomInTextField! * firstWholeInTextField! / firstDenomInTextField!

var secondStep = firstStep + firstNumInTextField! / firstDenomInTextField!

var thirdStep = secondDenomInTextField! * secondWholeInTextField! / secondDenomInTextField!
var fourthStep = thirdStep + secondNumInTextField! / secondDenomInTextField!

var calculatedAnswer = (secondStep + fourthStep)
var numerator = Int(calculatedAnswer * 10 * 10)
println(numerator)
answerLabel.hidden = false
answerLabel.text = printSimplifiedFraction(Numerator: numerator)
``````

printSimplifiedFraction Function

``````func printSimplifiedFraction(Numerator numerator: Int, Denominator denominator: Int = 100) -> String
{
var finalNumerator = numerator;
var finalDenominator = denominator;

var wholeNumbers:Int = numerator / denominator;
var remainder:Int = numerator % denominator;

//println("wholeNumbers = \(wholeNumbers), remainder = \(remainder)");
//println("\(denominator) % \(remainder) = \(denominator % remainder)");

if(remainder > 0)
{
// see if we can simply the fraction part as well
if(denominator % remainder == 0) // no remainder means remainder can be simplified further
{
finalDenominator = denominator / remainder;
finalNumerator = remainder / remainder;
}
else
{
finalNumerator = remainder;
finalDenominator = denominator;
}
}

if(wholeNumbers > 0 && remainder > 0)
{
// prints out whole number and fraction parts
return("Simplified fraction of \(numerator)/\(denominator) = \(wholeNumbers) \(finalNumerator)/\(finalDenominator)");
}
else if (wholeNumbers > 0 && remainder == 0)
{
// prints out whole number only
return("Simplified fraction of \(numerator)/\(denominator) = \(wholeNumbers)");
}
else
{
// prints out fraction part only
return("Simplified fraction of \(numerator)/\(denominator) = \(finalNumerator)/\(finalDenominator)");
}
}
