1. What must a ratio’s formula identify?
Show answer and why
Answer: Its precise numerator and denominator definitions.
Why: Different definitions can produce different values for an apparently similar ratio.
2. Why match periods, units and balance-sheet dates?
Show answer and why
Answer: They identify the quantities being compared.
Why: Mixing incompatible periods or units can produce a misleading interpretation.
3. Does one favorable ratio prove a company is a good investment?
Show answer and why
Answer: No. Examine the business, risks, accounting context and price as well.
Why: A ratio summarizes selected quantities and leaves out other important evidence.
Key takeaways
- Identify the precise numerator and denominator of each ratio.
- Use compatible units, reporting periods and balance-sheet dates.
- Interpret ratios alongside the business, risks, accounting context and price.
