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.

Yes.

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!
