Your teacher will give you a variety of newspaper clippings that include percentages.
Sort the clippings into two piles: those that are about increases and those that are about decreases.[br][br]Were there any clippings that you had trouble deciding which pile they should go in? Explain.
In the previous activity, you sorted news clippings into two piles. From the first pile (increase examples), draw a diagram that shows how percentages are being used to describe the situation. Increase Example:
For your example above, write [b][i]two [/i][/b]questions that you can answer with the given information.
Answer [b][i]each [/i][/b]of the questions you came up with. [i]Explain[/i] your reasoning.
