Which steps could be used to solve this story problem? The librarian was organizing some books on some shelves. She had 200 fict
ion books, 100 non-fiction books, and 38 magazines. She decided to put all of the magazines in a box. She put an equal number of books on each of 6 shelves. How many books should the librarian put on each shelf? A. Add together 200 and 100. Then divide the sum by 6. B. Subtract 100 from 200. Then add 6 to that difference. C. Multiply 200 × 6. Then subtract 100 from that product. D. Divide 200 ÷ 100. Then add 6 to that quotient.
Hi there! The answer is A. Add together 200 and 100. Then divide the sum by 6.
In this problem we want to know how many books there are on 1 shelf. Therefore we must first now the total amount of books and so we add up 200 and 100 (which makes a total of 300 books)
Finally we divide this total amount of books by the amount of shelfs (300 / 6), and then we've found the answer to our question. Hence, the answer is A.
