Since we are looking for books and tennis balls, we have to look at how many there are. There are 5 books and 8 tennis balls. We're looking for the ratio of books to tennis balls, so it has to be in that order. 5:8
For this question you should know: 1/2 = 5/10 and 4/5 = 8/10 so you can see 8/10 is greater than 5/10 so the answer is no 4/5 is greater than 1/2 :))) i hope this is helpful have a nice day
