Question

How many more squares must be shaded so that $\frac{1}{3}$​ of the figure is shaded?

Answer 1

In order for it to be shaded $\frac{1}{3}$ of the figure total of 4 squares have to be shaded.

In the given figure only 3 squares are shaded.

In order for it to be shaded $\frac{1}{3}$, we need to shade 1 more box.
