Explanation:
this question is marked as "college".
that cannot be. this is elementary school stuff, so, I hope you are an elementary school student.
remember what you learned about divisions of fractions :
a/b / c/d = (a×d) / (b×c)
so, "outer / inner".
you can also say
a/b / c/d = a/b × d/c = (a×d) / (b×c)
as dividing by a fraction is the same as the multiplication with the upside-down version of that fraction.
the result of a multiplication of fractions is then "upper / lower".
so, your problem here is
2/3 / 4/5 = (2×5) / (3×4) = 10/12 = 5/6
