i'm on 4.3 (and said so already, look again :-) ) so there's little hope. It seems to be possible to multiply rational fractions by passing them to pari, which returns a string, then parse the string with regular expressions to get the numerator and denominator, and then try :
result= sage.rings.fraction_field_element.FractionFieldElement( QQ['t'].fraction_field(), numerator, denominator, coerce= True, reduce= False ) (reduce= False being the most important thing) but it's a bit complicated isn't it ?
