We are given that Jenny can read 3 books in 7.5 hours. To find the number of books Jenny can read in one hour, all we need to do is divide 3 by 7.5, which gives us 0.4 books. Therefore, Jenny can ready 0.4, or 2/5 of a book in one hour. Hope this helped!

Hi there! To find the unit rate for the number of books Jenny reads, we can divide the number of books read by the amount of hours. 3/7.5 is 0.4 or 4/10 in fraction form. Jenny can read 4/10 of a book in one hour.
