A square is divided into nine smaller squares of equal area. The center square is then divided into nine smaller squares of equal area and the pattern continues indefinitely. What fractional part of the figure is shaded?

1/2

Step-by-step explanation:

In each square pattern, there are 4 shaded squares and 4 white squares. If the pattern continues on forever, the squares will continue to be divided equally, with 4 shaded and 4 white. Therefore, 1/2 of the figure is shaded.
