1.
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%.

2.
What percent of the figure is shaded?

 a. 30% b. 36% c. 40% d. 35%

#### Solution:

[Amount shaded] / [the whole] = 9 / 25

9x425x4
[Multiply both numerator and denominator by 4 to make denominator 100.]

= 36100 = 36%
[Express the ratio as a percent.]

36% of the figure is shaded.
