Answer 2

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`
