when constructing a graph that compares the land areas of the five largest countries, you choose to depict the five areas with squares of different
sizes. if the squares are drawn so that the areas are in proportion to the areas of the corresponding countries, is the resulting graph valid? why or why
not?

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.
