I WILL FAN AND MEDAL
Jake's band played songs at three different parties. At the first party they played four-fifths as long as they did at the second party, which was one-half as long as the third party. If they played for 6 minutes at the first party, how many minutes did they play at the third party?
Choose one answer.
A. 2 minutes
B. four and four-fifths minutes
C. eight and three-fifths minutes
D. fifteen minutes

So to make it all a bit simpler, you represent the first party as 'a', second party as 'b' and third party as 'c'.
c = 1/2 b
So they played 15 minutes at the third party.
