Explanation:

Answer 2

`(1)/(4)` of the books in the book store are mystery fiction books.

Explanation:

Let x represent all the books in the books store.

Then, the fraction of books that are fiction books is
`(3)/(4)x`

We have that;
`(1)/(3)` of the fiction books are mystery books.

The fraction of the books at the bookstore that are mystery fiction books is
`(1)/(3)* (3)/(4)x=(1)/(4)x`.

Therefore
`(1)/(4)` of the books in the bookstore are mystery fiction books.
