Total Earnings = Hourly Rate × Hours Worked

For a total volume of 48 cups, use the ratio to find: Red Raspberry = (3 parts / 4 parts total) × 48 cups = 36 cups.

Percentage = (Number in subgroup / Total number) × 100. For ninth graders: (20 / 46) × 100 ≈ 43%.

Probability = P(Event 1) × P(Event 2). For a cube landing on 4 and coin landing heads: (1/6) × (1/2) = 1/12.

A ratio is a relationship between two numbers indicating how many times the first number contains the second.

A 'fair' die or coin means each outcome has an equal chance of occurring.

Multiply the fraction by 100. For example, 1/4 = 1/4 × 100 = 25%.

Total volume is the sum of the volumes of all components in a mixture.

Independent events are those whose outcomes do not affect each other.
