In a bookcase, there are 6 fiction books for every 7 nonfiction books. There are 91 books in the bookcase. How many nonfiction books are in the bookcase? There are ____ nonfiction books in the bookcase?
OK.... 6 out of thirteen are fiction and 7 out of thirteen are non-fiction
How many sets of thirteen are there in 91 ?
91/13 = 7
7 out of thirteen are non fiction there are SEVEN sets if THIRTEEN 7 x SEVEN = 49 non-fiction books !
thanks
