For the first question: All you have to do is count the rectangles! So, not including the shaded rectangle, there are 14 that are equal in size. (If your teacher wants you to include the shaded rectangle in your answer, it is 15.)
For the second question: You just have to put the number of shaded rectangles (1) as the top number, or numerator. Then, you put the total number of rectangles as the bottom number, or denominator (15), to get you an answer if 1/15 of the square.
For the third question: the area of the square is 1 meter, so the fractional answer would just be 1/1. You could do it with the rectangles, too, and get 15/15 which reduces to 1/1 as your final answer.
Hope this helps! Good luck!
