Question

A cleaning crew can clean 5 offices in 6hours.how many offices can they clean in 12 hours

Answer 1

Set up a proportion like this
   $\frac{hours}{offices}$ = $\frac{hours}{offices}$
 
So your proportion would be:
  $\frac{6}{5} = \frac{12}{x}$
We put x for offices because they are asking for the number o offices a crew can paint in 12 hours, and also we don't know the number of offices they can paint in 12 hours
       so we cross multiply and we get
     6x=60, we got 60 by multiplying 12 and 5
Now we divide both sides by 6 and we get
  x=10
S the crew can paint 10 offices in 12 hours.
