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.

Answer 1

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.
