1. What is a Ratio Calculator?

Definition: This calculator computes the ratio between two values (a ÷ b), showing their proportional relationship.

Purpose: It helps in various fields including mathematics, engineering, finance, and construction to understand proportional relationships between quantities.

2. How Does the Ratio Calculator Work?

The calculator uses the formula:

Where:

• \( a \) — First value (numerator)
• \( b \) — Second value (denominator, must be > 0)

Explanation: The ratio represents how many times one value contains another, expressed as a decimal number.

3. Importance of Ratio Calculation

Details: Ratios are fundamental in comparing quantities, mixing proportions, financial analysis, and scaling measurements.

4. Using the Calculator

Tips: Enter any two positive numbers (b must be greater than 0). The result shows their proportional relationship.

5. Frequently Asked Questions (FAQ)

Q1: What does a ratio of 1 mean?
A: A ratio of 1 indicates that the two quantities are equal (a = b).

Q2: Can I use this for mixing ratios?
A: Yes, this calculator works for any proportional relationship, including mixing ratios for concrete, paint, etc.

Q3: Why can't b be zero?
A: Division by zero is mathematically undefined, so b must be greater than zero.

Q4: How do I convert the decimal ratio to a ratio format (e.g., 1:2)?
A: Multiply both sides by a common factor to get whole numbers (e.g., 0.5 = 1:2).

Q5: What's the difference between ratio and percentage?
A: A ratio compares two quantities directly, while a percentage expresses one quantity as parts per hundred of another.
