Hobbit land...

  1. Jan 4, 2016 #1
    1. The problem statement, all variables and given/known data
    In Hobbit Land, they use nicks, nacks and nocks for currency.

    2. Relevant equations
    3 nicks = 2 nacks
    5 nacks = 4 nocks
    7 nocks = 6 nucks

    3. The attempt at a solution
    How many nacks make 60 nicks? I got 40
    How many nicks make 80 nocks? I got 150
    How many nicks make 240 nucks? I got 525

    Am I correct?

    The first two are correct. There seems to be a typo in the third.

    3 nicks is 2 nacks:

    ##\frac{2}{3} \frac{nacks}{nicks}##

    Use dimensional analysis:

    ##(\frac{2}{3} \frac{nacks}{nicks})(60 nicks)##

    I'll let you correct yourself!

    @Samy_A ,
    This is one reason why some of us old-timers here at PF use the "Reply" button, especially when responding to the Original Post.
