Am I correct in assuming that "quilogramas" is feminine, but "quilos" is masculine? I get confused, as Spanish tends to keep the long-form gender for abbreviations. Ex.: la radio(emisora).
I'm sure I give the correct response but I cannot see what I wrote to check it out. I have complained about this several times before. Why can't Duolingo let us see what I wrote instead of greying it out so it can't be seen?
