Answer:

\frac{1}{4} of the books in the book store are mystery fiction books.

Step-by-step explanation:

The fraction of the books at the  bookstore that are mystery fiction  books is \frac{1}{3}\times \frac{3}{4}x=\frac{1}{4}x.

Therefore \frac{1}{4} of the books in the bookstore are mystery fiction books.
