Hadley decided to paint 4/5 of the rooms in her home last year. By the end of the year, Hadley completed 2/3 of the rooms. How much of Hadley's home was painted last year?

Answer 1

Since 2/3 of her home was painted, then 4/5 - 2/3 = 12/15 - 10/15 = <<12/15-10/15=2/15>>2/15 of Hadley's home was painted last year. Answer: \boxed{2/15}.
