Question

Of the books in a personal library, 2/5 are fiction. Of these books, 3/5 are paperback. What fraction of the books in the library are fiction and paperbacks?

Answer 1

In order to get the fraction of books that are both fiction and paperbacks, we multiply both fractions:

`(2)/(5)\cdot(3)/(5)=(6)/(25)`

This way, 6/25 of the books in the library are both fiction and paperbacks
