Two Associated Unit Rates
It is possible to write two unit rates for each situation involving rates. Thus, if a library contains 1200 books for every 75 readers, we can obtain the following unit rates:
Number of books for each reader (N1). We have
N1 = Number of books/Number of readers
= 1200 books/75 readers
= 16 books/reader
Number of readers for each book (N2). We have
N2 = Number of readers/Number of books
= 75 readers/1200 books
= 0.0625 reader/book
Since both of these unit rates belong to the same event, they are called associated unit rates.
