Question

The staff takes 1/2 of an hour to assemble 1/7 of the booths for a carnival. How long does it take the staff to assemble all of the booths?

Answer 1

t= time
b= 1 booth (7b = 7 booths)
x= total time (unknown)

1/2 hr ( 30 minutes) * 7 booths = 30*7= 210 minutes

210 minutes / 60 minutes (an hour) =3 1/2 hours

Answer 2

It would take the staff 3 and 1/2 hours
