So your proportion would be:

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

Now we divide both sides by 6 and we get
x=10
S the crew can paint 10 offices in 12 hours.
