Absolutely, we can calculate the ratio of squares to the total number of shapes. To find the ratio, use this procedure:
1. Count the number of squares: There are 3 squares.
2. Count the total number of shapes: There are 15 shapes in total.
3. Divide the number of squares by the total number of shapes:
That is, 3 divided by 15 equals 0.2.
So, the ratio of squares to total shapes is 0.2. It tells us that, out of every 5 shapes, 1 shape is a square.
