what percentage of the 100 square grid is shaded

Answer:
25%
Step-by-step explanation:
Simply count the fully shaded squares; there are 22 of them. Then count the 1/2 filled squares; there are 6 of them. Combine half squares to make whole squares and you end up with 3 full squares.
Add 22+3 to get 25 -- 25 out of 100 = 25%
Hope this helps!
