What fraction of these eight shapes are squares?

Now what fraction of these eight shapes are squares?

½ of the shapes are squares, ½ of the shapes are circles/ Two squares are replaced with two circles. Now 1/3 of the shapes are squares, 2/3 of the shapes are circles. How many shapes did we start with?

If 1/3 of the total number of shapes were squares what multiplication table will the total number of shapes be in?
