Asquirrel family collected 72 nuts to store for the winter. they spread the nuts out evenly between their 6 favorite locations. sadly, a crow stole half the nuts from one of the locations.

White shapes and black shapes are used in a game. some of the shapes are circles. while the rest 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 cicrles to the number of white squares is 3: 7. the ratio of the number of black circles to the number of black squres is 3: 8. work out what fraction of all the shapes are circles.
