In a certain Library, there are r bookcases with s shelves in each book case. If a total of b books is to be distributed among the shelves, What is the number of books per shelf?
a) b/rs
b) rb/s
c) rsb
d) r/s-b
e) b/s-r
b/rs
To determine the number of books per shelf in the library, we need to divide the total number of books, b, by the total number of shelves, which is r multiplied by s.
So, the correct option would be:
a) b/(r * s)
Explanation:
To find the number of books per shelf, we divide the total number of books (b) by the total number of shelves (r * s), which gives us b/(r * s).
