Andrew can do 4 times faster
So 1 Andrew is equal to 4 Bailey
1 Andrew and 1 Bailey = 5 Bailey

5 Bailey takes 9 days
1 Bailey take 9 x 5 days = 45 days

Bailey takes 45 days
Andrew can do it 4 times faster
so Andrew needs 45/4 days
Andrew needs 11.25 days

Andrew will take 11.25 days to paint the house.
Bailey will take 45 days to paint the house.
