How good are you at working with fractions?
How good are you at working with percentages?
How good are you at calculating a 15% tip?
How good are you at figuring out how much a shirt will cost if it is 25% off?
When reading the newspaper, how helpful do you find tables and graphs that are parts of a story?
When people tell you the chance of something happening, do you prefer that they use words ("it rarely happens") or numbers ("there's a 1% chance")?
When you hear a weather forecast, do you prefer predictions using percentages (e.g., “there will be a 20% chance of rain today”) or predictions using only words (e.g., “there is a small chance of rain today”)?
How often do you find numerical information to be useful?
