FAQs

Question: What are the basic properties of ratios?
Answer: Ratios compare two quantities and can be simplified like fractions. They maintain the same relationship when multiplied or divided by the same number.

Question: How do I solve problems involving direct and inverse proportions?
Answer: For direct proportions, as one quantity increases, the other also increases. For inverse proportions, as one quantity increases, the other decreases. Set up equations based on these relationships to find the unknowns.
