Question 1044439
If the ratio of Sinhalese books to English books is 5:3,
the English books are {{{3/(5+3)=3/8}}} of all the books.
Those are all novels.
Of the remaining {{{5/8}}} of the books, {{{1/10}}} are not novels,
and the other {{{1-1/10=9/10}}} are novels.
Since the Sinhalese books are {{{5/8}}} of the total,
{{{9/10}}} of them are novels,
{{{(9/10)(5/8)=9/16}}} of all the books are Sinhalese novels.
The novels are {{{3/8+9/16=6/16+9/16=highlight(15/16)}}} of all the books in the library.
