`2.5\ (people)/(book)`

Explanation:

The correct question is

The ratio of people to books in a classroom is 10:4 what is the unit rate of people per book?

Let

x ----> the number of people

y ----> the number of books

we know that

To find out the unit rate of people per book , divide the total number of people by the total number of books

we have

`x=10\ people\\y=4\ books`

so

`(x)/(y)=(10)/(4)=2.5\ (people)/(book)`
