The complete question is
Zach has 3/4 hour to play video games. it takes him 1/12 hour to set up the system. Each round of his favorite game takes 1/6 hour. How many rounds can he play
we know that
1) Zach has \(3/4\) hour to play video games
Convert to minutes
\(1\ hour=60\ minutes\)
\((3/4)*60=45\ minutes\)
2) It takes him \(1/12\) hour to set up the system
Convert to minutes
\((1/12)*60=5\ minutes\)
3) Find time available to play video games
\(45\ minutes-5\ minutes=40\ minutes\)
4) Each round of his favorite game takes \(1/6\) hour
Convert to minutes
\((1/6)*60=10\ minutes\)
5) Divide the time available to play video games by the time each round of his favorite game
\(40/10=4\ round\)
therefore
the answer is
\(4\ round\)
