Sudoku 86: Fraction Sudoku

Similar to last post, sharing a sudoku which I had created for practice for WSC for the Indian team. This time it is a Fraction Sudoku.

Rules: Put numbers 1/2, 1/3, 2/3, 1/4, 3/4, 1/5, 2/5, 3/5, 4/5 instead of 1-9 so that each number appears exactly once in each row, column and 3x3 outlined box. Letter N means that numbers in neighbouring cells have the same numerator. Letter D means that numbers in neighbouring cells have the same denominator. All possible letters N and D are given.
