Question

Zach has 3/4 hour to play video games. it takes him 1/12 hour to set uo the system. Each round of his favorite game takes 1/6 hour. How many rounds can he play

Answer 1

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

$4\ round$
