Final answer:
The ratios that measure a firm's liquidity are the cash coverage ratio, the interval measure, and the quick ratio.
Step-by-step explanation:
The ratios that measure a firm's liquidity are the cash coverage ratio, the interval measure, and the quick ratio. These ratios assess a company's ability to meet its short-term obligations and manage its current assets. The cash coverage ratio measures a firm's ability to cover its interest payments with its cash flow, while the interval measure evaluates how long a company can sustain its current level of operations using its liquid assets. The quick ratio, also known as the acid-test ratio, measures a company's ability to meet its short-term liabilities with its most liquid assets.
For example, if a firm has a high cash coverage ratio, it indicates that it has sufficient cash flow to cover its interest expenses. On the other hand, a low quick ratio could suggest that a company may struggle to pay its short-term obligations due to a lack of easily convertible assets.
