At a construction job for a theater, there are 30 painters. Of these painters, 24 of them are painting the interior of the theater. What percent of these painters are painting the interior?
Answer:
80 percent of the workers are painting the interior

As it says "What percent of these painters are painting the interior?" , the interior number is the second number and the total painters is the first number mentioned.
So let's put the values-
24/30*100=80%
The answer is 80%.
