Let total books be x.
number of fiction books = x/5
self-help books are 1/3 less than the fiction books,
=> number of self-help books = x/5 - (1/3)*(x/5) = (2/3)*(x/5)
so, their sum is = x/5 + (2/3)*(x/5)
= (x/5)*[1 +(2/3)]
= (x/5)*(5/3)
= x/3
number of fiction books = x/5
self-help books are 1/3 less than the fiction books,
=> number of self-help books = x/5 - (1/3)*(x/5) = (2/3)*(x/5)
so, their sum is = x/5 + (2/3)*(x/5)
= (x/5)*[1 +(2/3)]
= (x/5)*(5/3)
= x/3

When calculating the number of self-help books why did you did x/5 - (1/3)*(x/5) and not x/5 - (1/3). It just says 1/3 less than the fiction books so this seems valid to me. But I couldn't get the correct answer. What am I missing?
