The "X/Y Ratio" is a mathematical expression that compares two quantities, where "X" represents one value and "Y" represents another. This ratio helps to understand the relationship between the two values, indicating how many times one quantity contains or is contained by the other. For example, if there are 10 apples and 5 oranges, the X/Y ratio of apples to oranges would be 10/5, which simplifies to 2. This means there are twice as many apples as oranges. In various fields, the X/Y ratio is used to analyze data and make informed decisions. In finance, for instance, the debt-to-equity ratio is a specific type of X/Y ratio that compares a company's total debt to its shareholders' equity. This helps investors assess the financial leverage and risk of a company. Similarly, in science, ratios can be used to compare measurements, such as the mass-to-volume ratio in chemistry, providing insights into the properties of substances
