9. On the grid below, 7 small squares are shaded. What percent of the grid is shaded?

There are 10 squares in each row and column.
10x10 = 100 squares in total.
Since 7 are shaded, to find the percentage in decimal form, divide the number of shaded square by the total number of squares:
7/100 = 0.07
As a percentage:
0.07 x 100 = 7%
