Introduction & Importance
Calculating ratios with negative numbers is a crucial skill in mathematics, finance, and many other fields. This tool helps you perform these calculations accurately and easily.
How to Use This Calculator
- Enter two numbers, one in each input field.
- Click the “Calculate” button.
- The result will appear below the calculator.
Formula & Methodology
The formula for calculating a ratio with negative numbers is:
ratio = (num1 / num2)
If num2 is negative, the result will also be negative.
Real-World Examples
Example 1: Stock Market
If a stock price drops from $100 to -$50 (indicating a short position), the ratio of the drop is:
ratio = (-$50 / $100) = -0.5
Example 2: Temperature
If the temperature drops from 20°C to -10°C, the ratio of the drop is:
ratio = (-10°C / 20°C) = -0.5
Example 3: Debt
If a person’s debt increases from $10,000 to -$20,000 (indicating a negative net worth), the ratio of the increase is:
ratio = (-$20,000 / $10,000) = -2
