A school library has 600 books out of which 540 books are fiction what percent of the books are fiction

540/600 = 9/10 = 90%

To find the percentage of fiction books in the school library, we need to divide the number of fiction books (540) by the total number of books (600), and then multiply by 100 to convert it to a percentage.

(540 / 600) x 100 = 0.9 x 100 = 90%

Therefore, 90% of the books in the school library are fiction.

To find the percentage of books that are fiction, you can use the following formula:

Percentage = (Number of fiction books / Total number of books) * 100

In this case, the total number of books in the school library is 600, and the number of fiction books is 540. Plugging these values into the formula, we get:

Percentage = (540 / 600) * 100

Now, let's calculate the percentage:

Percentage = (0.9) * 100

Percentage = 90%

Therefore, 90% of the books in the school library are fiction.
