Answer:

$\frac{20}{36}$

Step-by-step explanation:

the total amount of squares within this square is 36

and the number of shaded squares would be 20

so if 20 squares out of 36 squares are shaded, then the fraction is

$\frac{20}{36}$

or 55.56%

(to find percentage multiply $\frac{20}{36}$ by 100)
