84% 84, percent of astrid's books are fiction. What fraction of astrid's books are fiction?

yuradex [85]

Let number of books by astrid's = x

Out of x , 84% are fiction.

So, Number of non fictional books = x - $\frac{84x}{100}$

= $\frac{100x- 84 x}{100} = \frac{16x}{100}$

→Ratio of number of books to fictional books

$=\frac{x}{\frac{84x}{100}}\\ = \frac{100}{84}\\= \frac{25}{21}$ ⇒[Dividing numerator and denominator by 4.]

→Out of 25 books by astrid 21 are fictional.

→ Number of fictional books by astrid = $\frac{21}{25}$
