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 comic books does Jim have?

Answer 1

First we need to set up some equations (J is the books Jim has, C is the books Charles has and B is the books Bob has)
J=3C
C=2/3(B)

Then we just plug in the numbers to find the answer
C=2/3(27)
C=18

J=3(18)
J=54

Jim has 54 comic books

Answer 2

First divide 27 by denominator which is 3 which then gives you 9 then you multiply it by the numerator 2 which gives you 18, then you multiply that by 3 which gives you 54
