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

Let number of  books by astrid's = x

Out of x , 84% are fiction.

So, Number of non fictional books = x -

                                       =  

→Ratio of number of  books to  fictional books

                                     ⇒[Dividing numerator and denominator by 4.]

→Out of 25 books by astrid 21 are fictional.

→ Number of fictional books by astrid =

because its not ur topic and its not for is for homework not that.

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus
