## Understanding Ratio

Ratio is a mathematical concept that quantifies the relationship between two or more quantities. It is a way to compare one quantity to another, often expressed as a fraction or a percentage. Ratios are used in various fields such as finance, science, engineering, and everyday life to make comparisons and analyze data.

## Types of Ratios

There are different types of ratios, such as:

- Simple Ratio: Compares two quantities directly.
- Compound Ratio: Compares multiple quantities.
- Proportion: Establishes equality between two ratios.

## Examples of Ratios

One common example of a ratio is the debt-to-income ratio used in finance. It measures an individual’s total debt relative to their income. For example, a debt-to-income ratio of 0.5 means that a person’s debt is half of their income.

## Case Study: Financial Ratio Analysis

In the business world, financial ratios are crucial for assessing a company’s financial health. For example, the debt-to-equity ratio compares a company’s debt to its equity, indicating its level of financial leverage. A high debt-to-equity ratio may signal potential financial risk.

## Statistics and Ratios

Ratios are also used in statistics to analyze data. For instance, the profit margin ratio measures the percentage of sales revenue that becomes profit. It helps businesses evaluate their profitability and efficiency.
