Study Notes
Chapter 6 Review - Short Answer
- Ratio Simplification: To simplify ratios, find the greatest common divisor (GCD) of the numbers in the ratio and divide both numbers by the GCD.
- Equivalent Rates: Determine the rate by converting units to a common denominator.
- Proportions: Determine if ratios form a proportion by using cross-multiplication. If both products are equal, the ratios form a proportion (e.g., a/b = c/d; ad = bc).
- Scale and Distance: Use the provided scale to find the actual distance (e.g., 1 inch : 15 miles; 5 inches = 75 miles).
- Geometric Similarity: Determine if shapes are similar by comparing their ratios.
- Probability of Spinner: Determine the probability of a spinner landing on a specific section, given that the spinner is divided into equal sections.
- Probability of Odd or Even Numbers on Spinner: Calculate the probability of the spinner landing on an odd or even number, contingent on the number of sections that are odd or even.
- Probability of Rolling Number Cubes: Calculate the combinations that produce a total greater than 8 when two number cubes are rolled.
- Odds Against (Event): Calculate the ratio of outcomes unfavorable to the outcomes favorable for a certain event.
