Review Ratios and proportions before starting →Ideas to recall
- A ratio compares two or more homogeneous quantities in a strictly defined order.
- Quantities must share identical physical units before forming a valid mathematical ratio.
- A proportion states that two ratios are equal, satisfying the cross-product rule ad equals bc.
- In direct proportion quantities scale together; in inverse proportion their product remains constant.
Use these ideas to reason through each question; answer-specific explanations appear only after you check a response.
