Some of the shapes are circles. All the other shapes are squares. The ratio of the number of white shapes to the number of black shapes is 5:11 The ratio of the number of white circles to the number of white squares is 3:7 The ratio of the number of black circles to the number of black squares is 3:8 Work out what fraction of all the shapes are circles.
the 2: 3 ratio is the length of the ac segment to the cb segment total length. this implies that the ratio between segment ac length and segment ab length is 2: 5. point c is 2/5 from a to b, so the required fraction is 2/5.
