6/8 because she painted half of her room in 3/4 of an hour and add half of that and you get 6/8! Hope this helps! Im not very good at math so don't judge me if its wrong...
it will take her 90 minutes.
there is 60 minutes in an hour and 3/4 is 45 minutes.
2 half (1/2) make a whole (1).
45 plus 45 is 90.

hope I helped
