Which of the grids represents 37%?

 a. Grid 1 b. Grid 2 c. Grid 3 d. Both Grid1 and Grid2

#### Solution:

Percent of the Grid 1 shaded = [Squares shaded] / [total squares] = 37 / 100 = 37%

Percent of the Grid 2 shaded = [Squares shaded] / [total squares] = 36 / 100 = 36%

Percent of the Grid 3 shaded = [Squares shaded] / [total squares] = 44 / 100 = 44%

Grid 1 represents 37%.
