Answer 2

Let number of books by astrid's = x

Out of x , 84% are fiction.

So, Number of non fictional books = x -
`(84x)/(100)`

=
`(100x- 84 x)/(100) =  (16x)/(100)`

→Ratio of number of books to fictional books

`=(x)/((84x)/(100))\\ = (100)/(84)\\= (25)/(21)`⇒[Dividing numerator and denominator by 4.]

→Out of 25 books by astrid 21 are fictional.

→ Number of fictional books by astrid =
`(21)/(25)`
