Answer:
<em>There are 1700 books in the library.</em>
Step-by-step explanation:
<em>If 28% of the books is non-fiction, that means the remaining 72% of books are fiction.</em>
If 72% of the books are fiction, 1224/72 will give us 1%, which is 17.
If 1% is 17 books, then 17*100=100% of books.
There are 1700 books in the library.

Simplify the following:
4×9^2/27×5
9^2/27×5 = (9^2×5)/27:
4×(9^2×5)/27
4×(9^2×5)/27 = (9^2×5×4)/27:
(9^2×5×4)/27
9^2 = 81:
(81×5×4)/27
81/27 = (27×3)/27 = 3:
3×5×4
3×5 = 15:
15×4
15×4 = 60:
