For this case, we have the total of painters is 16, so to determine what percentage is painting the interior of the house, we make a rule of three:

16 ---------------> 100%

4 -----------------> x

Where "x" represents the% of painters who paint the interior of the house.

x = \frac {4 * 100} {16}\\x = 25

Thus, 25% of painters are painting the interior of the house.
