Answer 1

Of 60 books on a bookshelf, 24 are non-fiction, 40% of the books are non-fiction, and the other 60% are fiction.

Answer 2

well, it's proportions, is over of so 24, is the is so that goes on top, 60 is the of that goes on the bottom, You dont know the percent yet, so its x over 100. you multiply x to 60 and you get 60x, then you multiply 24 to 100 and get 2400. you divide 60x to each side, when you didvide 60x to 60x it cancels out. when you divide 60x to 2400, you get 40. you divide it by 100 and you get the decimal 0.4. then you want to times it by 100 again and you get 40. so the answer is 40%
