Answer:
[tex]2.5\ \frac{people}{book}[/tex]
Step-by-step 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
[tex]x=10\ people\\y=4\ books[/tex]
so
[tex]\frac{x}{y}=\frac{10}{4}=2.5\ \frac{people}{book}[/tex]
