Question

A box in a college bookstore contains books, and each book in the box is a history book, an English book or a science bok. If 1/3 of these books are history books and 1/6 of these books are English books, what fraction of the books are science books?

Answer 1

1/2 are science because if you make 1/3, 2/6 + 1/6= 3/6. 3/6 = 1/2. 1/2 and 1/2 make a whole.
