50 books on the shelf are books of fiction.
Given that,
Becca put 91 books on a shelf. Of the books,28 were nonfiction,13 were poetry books, and the rest were fiction books. How many books were fiction is to be determined.
What is arithmetic?
In mathematics, it deals with numbers of operations according to the statements.
Here,
Total number of books Becca has = 91 books
Nonfiction books = 28
Poetry books = 13
When we add the nonfiction books and poetry books then subtract it from the total number of books then we get the number of fiction books Becca has. So,
Number of fiction books = 91 - (28 + 13)
= 91 - 41
= 50
Thus, 50 books on the shelf are books of fiction.
