Question 13: How many parts are the red boxes in the picture? Use a fraction to represent that part number. Choose the correct answer.

We see that the large square is divided into 16 small squares. And the red triangles are halves of the square

If each small square is further divided into 2 small triangles, the original large square is divided into 32 small triangles. and there are 4 red triangles

So yes \( \frac{4}{{32}}\) the square is colored in red
