Answer:
so the answer for the question is 1/4
Bob has 27 books.
Charles has two thirds as many books as Bob.
![27 \times \frac{2}{3}=9 \times 2=18](https://tex.z-dn.net/?f=27%20%5Ctimes%20%5Cfrac%7B2%7D%7B3%7D%3D9%20%5Ctimes%202%3D18)
Charles has 18 books.
Jim has three times as many books as Charles.
![18 \times 3=54](https://tex.z-dn.net/?f=18%20%5Ctimes%203%3D54)
