Answer 2

Answer:

Step-by-step explanation:

You are working with 1 large square made up of 100 little squares. The little squares make up 10 columns of 10 little squares each.

A

Shaded part = 30 squares.

Entire large square = 100 small squares

% = 30 / 100 * 100 = 30%

B

Shaded part = 20 horizontal squares.

Entire large square = 100 small squares

% = 20 / 100 * 100 = 20%

C

Shaded part = 5 by 5 little squares = 25 little squares

Entire large square = 100 small squares

% = 25 / 100 * 100 = 25%
