Hi

I am having difficulty in creating a function for subtracting fractions in a class. I was given this advice to do it

and my attempt is shown below:Note:subtraction can be achieved by adding (by changing the sign of the numerator - this can be achieved by multiplying it by -1).

but a subtraction seems to come out a little wrong for example the output is:Code:void Fraction::subtract(Fraction f2, Fraction& f3) { int s_denom = denom * f2.denom ; int s_num = ((num * -1) * f2.denom) - ((f2.num * -1) * denom); f3.create(s_num,s_denom); f3.simplify(); }

Can anyone help me to correct this little error.Code:Enter first numerator: 3 Enter first denominator: 4 Enter second numerator: 2 Enter second denominator: 4 3/4 - 2/4 = -1/4

Thanks if you can.
