Boris has 24 books and he donates a fourth of his books to the library. Cameron has 30 books and he donates a third of his books to the library. After donating their books, how many books in total do Boris and Cameron have together? Let's think first. Chain of thought:
Boris donates 24 / 4 = 6 books. Then Boris has a total of 24 - 6 = 18 books. Cameron donates 30 / 3 = 10 books. Then Cameron has a total of 30 - 10 = 20 books. Altogether, Boris and Cameron have 18 + 20 = 38 books.
Therefore, the answer is 38.
