Question

jim has three times as many comic books as charles charles has 2/3 as many books as bob bob has 27 books how many books do jim have

Answer 1

Jim has 54 comic books.

Bob has 27
So Charles has 18 (27*2/3)
Which means Jim has 54 (18*3)

Answer 2

If Charles has 2/3 of Bob's books means Charles has 2/3 of 27 OR

Charles has (2/3). 27 = 54/3 = 18 books.

Jimmy has 3 books more than Charles, then Jimmy has 18+3 = 21 books
